So after managing to run two sets of 8 minutes on Friday (which I'm both pleased and surprised about!), tomorrow is the dreaded 20 minutes run.
Did you manage to do it first time, or did it take a few attempts? Did you slow your pace down?
I run on a treadmill and usually run at 8km/h but I'm thinking about slowing down to 7.5km/h tomorrow. I'm loath to go any slower because I often find it harder!
