I have some lateral knee pain at the moment. I think it probably started after days 2 and 3 of my recent cycling trip, these 2 days being in the Italian Alps, and both days very challenging, so I suspect the cause of the pain is that I simply overdid the cycling. Although I managed 75% of the distance and 75% of the climbing during the 2 weeks of cycling over there, which I'm pretty happy with, it could have been more had the knee pain not made me skip some of the climbs. The problem is, I don't know how I caused this pain. Some internet reading tells me that misaligned cleats can cause it, e.g. on these 2 pages: http://www.bikeradar.com/au/gear/article/take-care-of-your-knees-part-2-17445/ http://www.bicycling.com/training/health-injuries/why-do-my-knees-hurt On this trip, I brought my own SPD pedals and matching shoes, so used the exact same pedal + cleat configuration I've used for years on my 180 mile per week commute. I was also careful to set the saddle height on the hire road bike to what I normally use, but obviously the geometry of the hire bike didn't exactly match my own road bike at home, or my commuter bike. It's also slow to heal: I did no cycling the week I returned from the trip, and now after resuming my work commute yesterday, I was woken up the middle of last night by the pain, and had to try to find a more comfortable sleeping position which didn't stress that area too much. Thoughts, anyone? Regards & thanks, --- Victor.
