Have you been in an cycling accident with injury?
Yes, more than a few times.
After your crash/injury how long until you were cycling again?
ASAP, but the "possible" has varied a lot. My big head injury - started riding rollers at week 15. On the road three weeks later. My first broke rib crash I was on the trainer in about 2 1/2 months. Next broken ribs, 1 1/2 months. Collarbones, three weeks or less.
Any changes in cycling since your accident(s)?
Not much.
