Bought my first road bike in July and my first crash was in early August. I was doing maybe 17mph, braking on a downhill in the wet while moving to the right over a painted stripe. Combination of newbie errors. Lost traction and the front tire slid into a conveniently located 23mm-wide groove and the front tube punctured; went down on my left wrist.
I got up, inspected self and helmet and a cyclist who saw he crash helped me out a lot by replacing my tube for me (I handed him my spare, pump and levers) and checking out my bike (only loss was a cosmetic cover part on the Ultegra shifter, and some scratches) - he happened to be an active racer, ex-mechanic(!) and still worked on his and friends' bikes. Got back on the bike and finished the remaining 2 miles of my ride. A few hours later the pain in my left arm was really bothering me so I left work and checked into ER and x-rays confirmed I broke my wrist + elbow.
I'd already signed up and paid for a century ride in mid-Sept so I still wanted to ride that. Doc cleared me to ride 2 weeks before it. It was fine except I couldn't use my main (front) brake or chainring shift as easily. Done a couple of metrics since then as well - I should hit 500 mi since my crash later this week. The pain is almost gone - it mostly hurts when it's cold out or when I'm doing a lot of climbing. The road rash scars aren't pretty but they're alright.
