The strategy for intervals will let you know what you are capable of and also to track your progress. Pete suggests that for the first (n-1) intervals do at a pace where you can manage to finish them then all out on the last, use the average as your target next time. The improvement might not be linear but generally you should see progress. Also, you may get instances when you blow up on the intervals from time to time.

Today I absolutely didn't want to do the 5*1500m but did it anyways with some DOMS in my hamstrings, started slightly slower and glad that I managed to neg split the intervals. The 1500m and 2000m are brutal, I don't like them but all the more reason to do them.
