just been for a run round the local park at work, tried using the mudrocs. I read a bit more about pose method on other websites, and tried the 180/min cadence, found I could keep this up for only 7 minutes (then my lungs were trying to pop out to have a look at what was happening!)I then did a few one minute runs at the 180, still quite sore with the calves, so will have to take it easy and steadily increase the time, came to the conclusion I must've been doing it completly wrong on monday. What sort of time scale should I be looking at getting back to my normal distances and times with running? (weekly mileage usually 30-35 miles, including a long run of 10-15)I didn't realise I was so unfit ref the burning lungs!!
