Over the last few months I have been working my way out of being a couch potato to hopefully some serious bike riding (we have a couple of 150km+ local events I have as goals to complete).
So over the last four months I have been building up my distances and increasing my average speed throughout (my main measure of improvement), just recently I moved from my aging MTB to a road bike and am new covering more distance faster than ever before
Anyway to my question, on Friday night I got in from a 25km hilly ride and was pushing my self more than usual, when I got in off my bike after a warm down I noticed I really stank, normally I am just wet from sweat but this was different, it was a smell I hadn't smelt for many years, last time was when I was on Outward Bound and the gear drying room had the same smell, I had always assumed it was just a mix up of everyone's odors on wet or damp gear. The catch here is I had showered ans everything was clean on before the ride.
That got me thinking is this due to something my body is doing differently after some harder than normal (for me) exercise?
