Nerve damageI am still having some serious problems with my ITB in my right leg. I have had my bike setup checked and re-checked and I am happy that my setup does not seem to be my problem; I have also seen several physios and sports physician's and the general consensus is that I have some functional differences that need to be sorted out and that this will take a lot of time. The current physio that I am seeing explained to me that my right hip is forwardly rotated and lower. When I stand with both feet together and go down my leg on the one side with my hand I can reach further on my right side than when I go down on the left side. He also gave me a wedge that I have to put in on the right shoe that lifts my right heel and part of the side of my foot. I wear this in my cycling shoe as well as my everyday shoe. The problem that I have is that after several weeks (six) of this and some good training the problem has now come back again, and I feel that my main problem is that no one seems to be able to understand what I need to do to help me sort out this while I am on the bike! Is there any way that I can make changes to the bike to make it possible for me to ride while we are trying to sort out these differences and get me straiten out. My current physio has made some suggestions that they want to try and build up the saddle on the right side, but I am not sure if they understand exactly if this would be the right thing to do - to try and relieve the strain on the ITB. Someone also suggested that I get and operation where they gut the ITB (Is this an option?) I'd appreciate any advice I can get. Willem South Africa
Choosing shoesI have written in before about knee tendonitis and related issues, and I have another somewhat related question: Do any of you recommend or counsel against certain brands of shoes with respect to functionality and pedalling technique? I have tried Sidi (so, so), Carnac (I liked these to some extent, but I believe they were half a size too small), and DMT (favourite so far). I should probably note that I use Sole custom footbeds in my cycling shoes. I need a new pair of shoes and am trying to decide what to buy from a functional standpoint. Are the new Carnacs lower stack height better functionally than before? Thank you very much for your time. Chris Barker
Leg lengthSteve, You stated to a reader on October 17, 2005 that, "The other consideration you need to think about is how this discrepancy has caused your pelvis to compensate. Many people like yourself, with a long right leg, will end up with an anterior iliac crest on the same side. This typically means that you may be sitting further forward on the seat with the right side of your pelvis and reaching a lesser distance to the pedals with the longer leg. To find out whether this is happening, fit your bike to an indoor trainer and while pedalling in a bigger gear, have someone positioned above and behind you look down at how square you are on the seat. You may not twist to the right because not everyone who has a long right leg does, but enough that I should mention the possibility. If you find this is the case, get back to me for further advice." Well, I have experienced that on my trainer. At first I thought that there was some alignment problem with my frame, or the trainer was warped, and I would always wear a hole on the inside of the thigh of my shorts because of the discrepancy. I eventually realized that I have a leg length issue myself. The left one being longer than the right. When I used to run, my right tendon just above the tensor fasiae latae would
become agitated and inflamed and hurt for several days after, affecting my gait,
especially when walking uphill. It has since stopped occurring, but I think
that is from unconscious compensation. Gavin Douglas Louisville, KY
Power cranksThis is a question for Mr Hogg who did such a fine job making me more comfortable on the bike. I have been using power cranks for almost six months now. I have never been able to ride more than 60 miles with them before my hip flexors give out completely. While I feel that I am very comfortable using regular cranks (no numbness in my hands or perineum, minimal neck or shoulder stiffness on century rides) I know my pelvis is very unstable with the power cranks. Both bikes are set up exactly the same. I am more stable with slow cadences but once I increase the cadence above 90, stability decreases dramatically. I think that if I lower my seat or move forward (both will likely decrease the work of the hip flexors) I would be more stable, but don't want to change my position with regular cranks. I also under use my quads/glutes in direct proportion to cadence which is similar to the prior posts. You probably do not recall but my left leg was always weaker, smaller and less efficient and the power cranks do help equalising my legs. Have you had time to ride a set, and do you have any ideas?

Heel position asymmetryFirst off - the fitness and training forum you support is outstanding! I've just stumbled on it today and am going blind trying to soak up all the insight and advice. I wish I had these words of wisdom 20 years ago. The fact that your team takes the time to consider questions carefully and respond with such detail and genuine concern is all but choking me up. I'm 40 years old, male, a road and mountain biker (done a variety of races on/off over the past 15 years as a club team level rider - just for fun). I'm admittedly heavy at 200 lbs and 6 ft. I've ridden my body hard and as a teenager, I broke up my left femur in a gnarly motocross race accident and had two surgeries for it. Cycling generally helps and I always feel best when I'm on two wheels. I've never been measured for a leg length difference - can it be done at home? Oddly enough the leg I broke is trouble free and the other has been problematic for years. When I first started road biking with fixed clipless pedals, I set my fixed cleats to be symmetric and I developed show stopper pain on the inside of my right knee. After some research, rest, and recovery I repositioned my right cleat to the max possible heel out position afforded by the pedal. The sensation was that my heel would like to be further away from the frame but my knee was now happy enough to at least continue cycling. This change, along with pre-ride stretching was adequate to keep me riding but the problem, while improved, persisted along tolerable right ankle soreness and obvious sense of body asymmetry. It was a balance between knee and ankle discomfort (I knew I could find pedals/shoes that would allow my heel to rotate further but I suspected my ankle would not hold up) and I'm sure I looked pretty strange with one heel roughly parallel to the longer bike axis and the other swinging into outer space. Subsequently, I've used or tried a number of different pedals and shoes over the years but SPD or SPD-R (each with the floating cleats positioned as far back on the shoe as possible and as heel out as possible on the right foot) have been the only compromise (SPD - small contact area or SPD-R discontinued) that has worked out. When I tried the Speedplay Xs years ago, I was amazed at how far my right heal wanted to go and how much rotational movement it tended towards. Look ARCs seemed too sticky and I felt like I had to consciously reposition and tweak my foot to the seated sweet spot after any unseated effort and I had pronounced right ankle soreness. (I noticed a recommendation to trim down the rubber pad in the middle to free the float a little, but doesn't that lead to vertical slop?). The times I tried had spring to centre float and no cleat rotation adjustment - worked for the left leg but the right was obviously fighting the spring. Summarizing, my left leg has been robust and insensitive to any pedals I've tried (Look, Time, Speedplay X, SPD, SPD-R) but SPD and SPD-R with limited float have worked best for the right. By the way, I've always ridden SPDs on the mountain bike with both cleats at max aft on the shoe and max heel out on the right - never had any significant problems or discomfort with that setup with looser and generally softer shoes. Based on the posts I've studied, I think one root cause theory having nothing to do with past injuries (best case maybe) is that I have a significant varus on the right foot that I naturally compensate for with heal rotation. The heal rotation relieves some knee strain at the expense of ankle strain. The SPDs have been more agreeable than other shoes because of their narrow and small contact mud shedding heritage allows for a less rigid connection and a little more freedom for the foot motion in roll. The float characteristics of SPD, free but limited in range, allow for sufficient and necessarily limited, heel out range. I got pretty excited about the possibilities when I read a post by Steve Hogg where a guy had a similar heel out thing going on. He stated that as his Look cleat wore down on the outside from repeated road contact his heel migrated back towards the frame. Could it be that simple? Does that suggest a wedge under my right cleat (fat side nearest the frame) would likely bring my heel in and restore some symmetry after all these years? If so, is it also likely that my right foot will also be more stable (roll and rotation), making it worth another try with a modern relative wide contact Look or SPD -SL pedal? Apologies for the long history and thanks in advance for your thoughts and recommendations. Bob Nantz Patuxent River MD
Moving cleats backThanks to Steve Hogg I moved my (Shimano Ultegra) cleats back about 5mm and noticed an improvement in the way my quads feel post-ride after two rides. Less of that dead feeling for sure! What I would now like to know is what do I need to do with my saddle position if I move my cleats back 5mm? Lower saddle by about 2mm to compensate, or move it forward by about 5mm to compensate for the modified leg bend angle? Should I do both or neither of these? I ask because I notice a different feeling as I am pedalling (I can't quite explain it yet) but perhaps this is normal and something I will get used to and therefore I should not change my saddle position at all? Thanks you very much in advance Yuri Budilov Melbourne, Australia
Spot reducingI'm a 45 year old competitive male cyclist, starting my second season of winter training. At 6'1" I currently weigh about 180 and lost about 20 lbs since the start of my cycling about two years ago. I try to eat healthy, but I don't diet and have not changed my high carb eating habits since starting cycling. With a reading of about 17-18% body fat (according to a fat measuring electronic scale), I still apparently have some room to lose more weight and increase performance if I can maintain the same power. One concern I have is that most of my weight loss tends to come off the face, arms and legs, with these areas looking very lean (especially face) and other areas, such as chest and back storing more of the fat - although it is uniform. I realise that common thinking is that you can't spot reduce, but I'm wondering if there is any truth to the tale that some types of foods store fat more readily in the trunk area. I guess I'm not overly concerned, but if I were able to lose enough weight to reach my 10-12% fat target - which is not that low compared to most competitive cyclists, I think I would look like a zombie.

Re-occurring shinglesCyclingnews team, I have been a competitive cyclist in all disciplines for over 20 years on and off, and have at my best raced in Belgium on the road and won age group medals at international duathlon events. The problem at the moment is a re-occurrence of shingles when I start my higher intensity workouts. This time around my base period has been about three months long and I have steadily increased duration up to around 18 hours a week max. I had a heart rate cap of 160bpm (max 190bpm). This base period came after a four-month layoff due to another bout of shingles while training for the duathlon world's. During this time I was still active but completed no structured training. I am fully aware of the correlation between overtraining and immune suppression; however, I monitor health and vitality, check morning pulse rate, eat very well and get good sleep so I just can't put my finger on the problem. Is shingles something that affects many athletes? And if so how is it treated? I am on an anti-viral medication called Valtrex at the moment. Is it possible to continue with light exercise or will I delay my recovery time? Also when do you know when to get back into it again? I am 35 years of age weigh 70kg, VO2max at beat 74ml/kg/min and at best have a power to weight ratio of 6.5watts/kilo, (I also have a degree in exercise science). Any help to allow me to get back to my best would be greatly appreciated. Mark
Recovery from a broken wristHi, I fractured my scaphoid bone during a MTB stage race in the Alps this last summer, doing a nice superman into a patch of asphalt. The race doctor wrapped it (thinking it was a sprain I suppose), gave me some pain killers and I continued racing and training for three weeks. In spite of this ill-advised punishment of my feeble wrist, a cast seemed to do the trick when I eventually got it properly treated. After about seven weeks, I was ecstatic to learn the fracture had healed. I had avoided the dreaded possibility of surgery and I could supposedly jump back on the bike - yeah! The problem is that now, going on four months after the injury and a month after the cast was removed, my wrist is still very painful. I find it difficult to hold MTB bars on semi-rough terrain, paddle, XC ski, or even carry my small daughter for long. It aches and the range of motion is still limited, although very slowly improving. I am sure you have seen your fair share of broken scaphoids. So, presuming the bone really is healed (which I am getting rechecked now), is this typically a traumatic injury from which it takes a very long time to recover? Might therapy of some kind speed up recovery? Presently I am limiting my workouts to lots of running and a bit of easy swimming. By the way, I am a 35 year old who, as you can see, sometimes has a hard time stopping...in every sense. Rick Van Camp Finland
Cleat positionHi there I'm a 41 year old male vet cyclist who has been having problem with what can best be described as "hot feet" when riding beyond a few hours. The area around the balls of my feet gets progressively sore to the point that it is difficult to stand while riding. I prefer to stand while climbing but there may well be a simple explanation for this. I recently read your posts about cleat position and now realise that I may have been mistaken to follow the old adage about positioning the ball of the foot over the pedal axle. If anything, the ball of my foot was very slightly behind the axle. The problem has probably been exasperated by my laid back seat position (10cms behind the bb) but I guess that is all relative to my rather long leg length. I have a 90cm inseam, with the upper leg (hip to knee) of 46cm, and lower leg of 56cm. One other detail is that I ride 180cm cranks. Anyway, I have just gone to adjust my cleats back and have found it impossible to get the ball of my feet as far forward of the axle as you have recommended. The furthermost forward I can get is 7mm, well short of your guide-line of 11mm. I use Shimano SPD SL shoes and cleats and my feet are size 46. Maybe I have excessively long toes? The distance from the tip of my large toe and the center of the ball of my foot is roughly 85mm. My shoes are a good snug fit in width and length so it is not just a case of the shoes being too big. Short of changing shoes and possibly pedals I can't see a way around the situation. The other related question is, 'If I change my cleat position do I need to also make changes to seat height and fore-aft seat position. I have played around with a few simple levers etc to see what effect a change of about 10mm would make to my knee position and it seems to me it is very minimal to virtually nothing at all. What is your take on this? Many thanks in advance. Terry Macpherson New Zealand
Terry then responded: Hi again Steve, Thanks for your comments. I have had another look at the position of the ball of my foot relative to the pedal axle in the new cleat position. The distance measured is clearly dependent on the position of the foot. I'm just about to head out for my first ride with the new cleat position so it will be interesting to see if I begin to notice some changes - hopefully no pain in my feet for starters. Many thanks for your help. Terry
Training with powerHi there. A question about training with power for the coaches. Assume that at the start of a training program, a rider does a test to determine LT power output and power zones for interval training. One would hope that as the training program progresses, power at LT improves. Is there a simple formula for determining how to factor improvements in power output into power zones, or is regular (monthly or so) testing the answer? Thanks. Andrew McRae
