As of last weekend I can finally run 5k on a treadmill (not continuously though, I had to take a 3 minute break at 3.5k to walk). I had the treadmill set at a 1% incline and ran it in just under 33 minutes (not including the walking break). I mostly only run once or twice a week (I do an hr long spinning class on one other day) so I am pretty happy with my progress although I intend to spend the next few weeks working on reducing the walking bit in the middle. Hopefully by the end of October I will be able to run 5k at the same speed without stopping and at a 2% incline.
I have only really dabbled at road running as it seems to give me knee problems but I have a little seed of an idea in the back of my mind that I would like to train for a 13k run next summer. The course is very hilly so I'm not sure if training on the treadmill will be adequate but also I don't know if my knees will hold out for weeks (or months) of road training. And will I be vewry disappointed by how little distance I can cover on the road compared to what I'm able to do on the treadmill?
Any advice most welcome.
