Day after burning in my quadriceps. Good?
I'm trying to ride harder, pushing up shorter, steep hills for under a few minutes pretty much until I crack. This has been producing a burning sensation in my quadriceps, nothing unbearable, but I was wondering what it is. I cooled down and stretch at the end of my ride to try and begin training right. Is this sensation normal? I'm looking at starting interval training this week and I feel like this could be a recurring thing. On a related note, is there a de facto training guide, a la Carmichael or some other trainer/author?
