Thanks for all the advice. saw the physio yesterday, smilar advice to 'chasm54' - no exercise until the initial healing has occured, then get on the trainer and spin lighly and see how it goes. Apparently six to eight days is the time frame.
Nightshade, yes, it does look like I'll miss the ride and I will get over it, but it's disappointing after being solely focussed on it for so long. Good call though, move on and set a new goal. Thanks.
