Hi jolyon,
That sounds quite good: 135 rpm. How longsince the accident? I am positive of mind, like most sporty people. But this injury is pretty awefull. Instill need some time now and then to rethink the consequences for the future. My favourite sport is cycling...if i can do that again i am happy. Running was more out of convenience of time needed.
Based on the stories on this site i just ordered a home trainer to practise daily...did it one time In the gym as a tryout, but until mid feb imam not allowed to drive.
Take care.
Dimitri
