Interesting Cross country Training

Hello It’s Dezray here from Paihia School. In Te Ngahere we have been doing cross country practice, we have to run for 15 minutes without stopping but me and my mates just walked most the way tho. We ran  2 laps but then we walked and talked for ten minutes it was really fun, next time I am just try to run most of the way now. Have you run 15 minutes straight before?
