Notice that OP stated
up to 5 times a week. This would imply that he did not do this week-in and week-out. Nor did he state that he raced 5 days per week. By competing in different categories, an active racer can easily book 2 races each on Saturday and Sunday, then add a mid-week crit.
Why is this so unbelievable to you?
While I certainly don't doubt the relative huge-ness of your quads
, what the OP has described appears to be more a case of muscle strength imbalance and not an explicit "weakness" of his quads. The VMO must pretty much work solo (against 3 other larger muscles, no less) to help keep the patella tracking correctly. Obviously, cycling is a great way to build leg strength, but due to the accepted (and certainly valid) seated pedaling position, the VMO can easily be neglected and therefore perform "weakly", relative to the other 3 muscles in the group.
