Even with a fairly bad collar bone break it’ll heal well and be as good as new if you treat it right.
The crucial stage is from day one to around ten to fourteen days. During the later part of this period you’ll get what’s known as a ‘fibrous union’. After that it’s just a hardening off process.
So, for the first couple of weeks do very little, rest and give it a chance. After that, assuming no complications, you can start turbo sessions. Pretty soon after, around the three week mark, that you can go for gentle rides (think, roadie towpath style). But, if you fall of and land on it you’ll **** it good so be careful.
By six weeks you’ll be back riding normal – but be careful, make it progressive. After two months, it’s fixed, and it’ll never break in the same place again.
All the above assumes that you are normal healthy sort of geezer.
There are those that say that you aren’t a proper cyclist until you’ve broken a collar bone.
