OK - so this past year I've bumped up my mileage to maybe twice the amount I used to ride.

And I can see the change in my legs! If I tense my thigh I can see this "ridge" of muscle running diagonally along the top, with an obvious "valley" running parallell to it...

That may not sound so strange, but I've been fairly fit and the same weight for the last 6 or 7 years, (plus minus a little round the middle ) and seeing my body changing shape is, well - just a little bizarre. But hey - I like it!

Anyone else notice changes like this just from increasing mileage?
