I am training for my first IM - Cozumel just a month away.
Lately, I have been experiencing knee pain after my longer bikes (80 miles +). The issue has been going on for about a month. Pain is not present walking or running, but will almost drop me if I bend it past 90 degrees. I have had the issue is both knees now. It started in my right and lasted for a few weeks. The pain eventually went away, and now has started in my left knee.
What are the main things to look for to help solve the issue? It has never been a problem when training or Olympic and 70.3 events in the past.
Also, I have never had a professional bike fit - just trolled around Slowtwitch and adjusted myself. Is it too late at just over 30 days out to change now?
