I am wondering just about hills. I live in northern california and there are an awful lot of gnarly hills here. I used to ride some mountain bike, but now I just switched to a road bike. I think I'm going to continue with road biking and commuting everyday as I have been, so my question is how to train for hills. I could ride forever here on the flats, but when it comes time to hit the hills, my legs flat feel like they're going to give out on me sometimes. It burns so bad, but I just push through them. I'm wondering if there is any way to get through the burning, or if that just comes in time. I've only been commuting about 2 weeks now, and I'm still getting used to it. Any help would be great
