I'm curious because I'm new and to ME a long ride for my legs is 10 miles. Then I see people who do 150 miles and live to tell the tale! I know I'll get there - it'll just take time.
So I'm curious, when you're riding, what is a long ride FOR YOU? Not what you think should be considered a long ride (I know 10 miles isn't long for most people), but more when your body start going, "AAAAAAH!" and not in a good way.
I'm interested to see where everyone falls on this!
