Halfway split in a 5k race

Hi everyone, I've entered the next Swansea Harriers 5k and I've been having a couple of practice runs along the course as I live very near to it.

I'm quite suprised by the difference in my halfway split times with the second half being a lot quicker.

My last try I did the first half in 14 minutes and the second half in 9 minutes and the second half was really enjoyable.

I don't know if its the fact that I can see the finish so know how hard I can push or whether I'm not getting a good enough warm up, but the second half is just so much better.

I'm going to try and push a bit harder in the first half next time but I suspect I'll suffer for it in the second half and probably run a slower overall time.

I'll just have to try it and see I guess.

Cheers

Sounds like the warm up effect, but I can really usually only speed up to max in a race when I can see the finish, so if you really can see the end from half way who knows?

Sounds more like a following wind and downhill in the second half.

Its a dead flat course and it wasn't windy, I'll try a longer warm up and see what happens, might try tomorrow morning as its supposed to be a nice morning although you wouldn't guess so at the moment its pouring down.

How do you know where the halfway point is? prehaps you are misjudging the distance?

Are you sure thats the right half way point then ?

First half at 10.7 kmh.

Second half at 16.7 kmh.

Sounds unlikely ?

Its an out and back course so its roughly halfway, although you do pass the start by a little bit its not much.

I had a go at going out faster this morning and got to the turnaround in 12 and finished in 23.19 but it was a much harder run and not half as much fun.

In a race I think I'd prefer to run it like I did the other day and have a slower start and hopefully be passing a few people on the second half instead of struggling back like today.

I'm the same on a measured 10k (there and back all flat on canal)that I've done the last 2 sundays.

Overall speeds are far slower than yours but the ratio isn't far off.

I only walk and stretch for a warm up and I think its part to do with that as the fist 1k always feels the hardest. The other thing is that my main concern is simply to do it so I can't help but be conservative on the way out but psycologically I'm happier to push myself when past the halfway mark.

Steve - sounds like you need a good warm up before you start - so its quicker to hit your running pace when the race begins. You'll tear through the field if you can do that.

I know negative splits are quoted as being very important for running marathons (not that I've ever managed it) but for a 5k I think it should be flat out all the way.
