Ok so I finally got my bike from my shop and I have a few questions after my first couple of rides. The first question is how do I build up my tolerance to lactic acid build up. It seems that at the ends of my ride my legs are on fire way more than throughout the rest of the ride. It gets to the point where I have to stop pedalling for 30 seconds to let it subside and then I can continue pedalling for 2-3 minutes. I don't really want to take a lot of breaks, Id rather pedal the entire ride. Is it as simple as increasing my distances and eventually my body will become climatized?
The second question is about bike shorts. I have a pair because I was warned they really help however after my first two rides of 8 and 14 miles(starting out small) my bum is just killing me. Is it the shorts? Or do I need to get use to that as well? Any recommendations for shorts or pants would be great!
