I have been doing interval training for a while now (running) and as I upped my speed I have also upped the time I run, I am running about 60 mins. at 5 min. hard 2 min easy. I have noticed I don't seem any faster and wondering if I should decrease the time I am running and keep increasing the speed????
I am only doing sprints so 3 miles is it, but I can't seem to run 3 miles under 30 min. Any ideas?
