I did not get my run in over the weekend so I was forced to do it on the treadmill this morning. It was a five minute walk (warmup) then run for eight, walk for five and run for eight. I cut off one minute of the middle five minute walk and added it to the eight minute run. I had no problem doing the nine minute run. I messed up by not pressing the start button on my watch so it shows that I was on the treadmill but the minutes are not showing.
