I find it is dead on for me in predicting a 3k from my 1500m time. However, it is considerably off on the longer distances. For example it predicts a a time that is 20 sec. slower than my actual time for the 5k. Should I assume that the same will be true for 10K as well?
I am running a 10k pretty soon and would like some feedback from others who have used this calculator.
Thanks.
