Hi,
Just latched on to C25K and reckon, since I've been keeping fit and playing sports for more years than I can care to remember, that I'm at level 5. However, because of my age and too many years of putting a lot of strain of on my knees, am doing the running/walking in the gym. What sort of speeds do you all reach when your running - it's easy for me to keep tabs on my speed and I seem to have settled on a running speed of between 8 and 10 kms. per hour - is that too slow?
