I am on week three of the ragnar training. it isn't much different from week 1 and 2 except you need to do a saturday run as well. 15 min doesn't seem like a long time, but you tend to push hard when you are only running that long. this next week i am going to rebel from the ragnar training and run 20 min a day. good luck to everyone who is running in the raspberry days 5k. it will be a tough one.
