What a lovely forum this is.
I am on W2 and have been doing the C25K on a treadmill (plan to head outside over the next couple of weeks).
Was wondering if anyone else out there is using a treadmill? If so, what speeds are you walking / jogging?
I have been walking at 5.2kph and jogging at 6.3kph, which was fine for W1, but I found W2R2 really difficult tonight. My muscles felt tired, and not really up to the job! (in fact I didn't actually complete all the runs). Not sure if it's because I had a really busy week at work, or if I'm going to fast for my level of fitness?
Any thoughts would be most appreciated.
