A few little details to report, but not much proper progress.
I managed to borrow an exercise bike (thanks Rudy), and have been doing two 20 minute sessions a day. Sometimes while watching the Tour De France on TV. Althought I've kept the resistance low, it's been great to actually get my heart and lungs working, and even break sweat. According to my heart rate monitor, I've been getting my heart up to around 100bpm, which is ok for now.
I also swapped some emails with Andy Mackay, who was the chief sector marshal at the point where I had my accident. I asked him how I crashed (as I have no memory of it), and he replied with the following:
As for what happened, well, you appeared to come into the kink before the bridge too quickly and when you realised you'd overcooked it you sat up and grabbed the front brake. When passing our point at the end if the coast road your back wheel was a couple of feet into the air and you were starting to go over the front. At this point you parted from the bike and it scuttled off to the left, clipping a bank and running back across the road and hitting the other side quite gently. Unfortunately, that was the only gentle bit of the incident. You, having parted from the bike, flew through the air at about six foot straight into a telegraph pole, which I swear is now bent backwards slightly! The pole protector was hardly marked by the way, so thanks for that! Given the force of the impact we initially feared the worst, but we never give up, so on reaching you we got to work and one way or another got you sorted and away in the ambulance (with a Police escort no less!). As the scruts needed to take the bike and measure up the scene, and we had to do statements for the Police, things were a bit delayed, but once we got underway again we soon got messages back through the Police and the Medics that you had perked up a good bit on route to Nobles, which cheered us all up no end!
As I've said before, if it wasn't for Andy and his team, I wouldn't be here now, so I obviously owe them a great deal. I shall try to repay them, in beer, next time I'm on the Isle of Man.
I have my next appointment with Mr Holt, my leg consultant, a week tomorrow. This will be 10 weeks (and a couple of days) post-op. We'll see what the x-rays reveal this time...
