Hi everyone,

I'm new to cycling. I've noticed that after my rides 10 - 30 miles on my road bike, strange bruises appear on my thighs (and a few on my calfs too)...smallard small and others are large and menacing looking. I haven't fallen or bumped my legs. Most of the bruises aren't painful. I just had a regular check-up this week and thankfully i'm healthy. What do you think is going on and what can I do to prevent this? Thanks!
