I completed all my runs last week, running at 4.5 mph. I now want to up the speed before considering upping the distance.
At the weekend I did 30 mins at 5 mph (which nearly killed me but never mind!)
Today I decided to do intervals of sorts - run 4 mins at 5.5mph and walk 1 min at 3.5 mph which I repeated 6 times.
So which is better? I found today easier apart from the last run.
I eventually want to be able to do 5k in 30 mins which means I need to up the speed to 6mph.
I also know I need to increase the incline on the treadmill or run outside but I plan to do those once I am running 5 k in 39 mins.
Any suggestions gratefully received and I hope the above makes sense!
