Tricky Whippet, it is an interesting thing to think over.
I must admit my style (if you can call it that
), is to burn off a bit too fast, settle, and then end.. a little too fast ...
What doesn't help in my summer 5k series is that the courses are either road and undulating, or multiple lap grass courses. Neither is ideal for good level racing.
Therefore, as well as natural too fast start, a couple of the races start gently downhill! Therefore, you end up having the incline when you're pushing hard at the end and working to your limit!
I was going to post splits from last year, but they'd reveal nothing as one of the races had a 3.03 first k and a 3.45 5th k. One was gently downhill, and one was obviously the finish, up a steep and short incline!
Might be interesting to test a couple of strategies this summer.
In one of my 5ks last year, I tried to race the winner. He's a 16.30 5k man, a 1hr 14 half man, and I was 17.20s and 1hr 19 at the time
