London Marathon Question; Equal Or Negative Splits, which Is Best?

Last year I tried for negative splits, but was unable to increase my pace in the final 6 miles.
Looking at the route profile and from running the race 7 times I know there is more downhill in the first half, so I feel an equal split would work better.
What do you think?
thanks for all comments.

I am aiming to run a negative split off a pace that would ensure a narrow PB if I just maintain the pace. Negative split in Florence last year felt amazing and I am absolutely sure this is the way to go whilst I also think it is good to have a backup plan in case the conditions mean that it is not possible to pick up the pace towards the end. Good luck by the way!

No idea, but negative split by 'effort' would be my call if I had an idea. Roberto's your man.

I reckon when you do PB it is most likely that, that will be with a second half negative split.

If it is going to be your day you'll know it by half way and if you are still on target by the 35km mark I gaurantee that nothing will stop you going for it and pulling out a strong negative split!

How about setting off far too fast- getting to halfway way up on schedule but tired - then you can take it easy for the tough second half?

I'll get me coat.

The conventional wisdom is even pacing by effort which, for all but the elites, means running the first half about a minute faster than the seconds half. I don't know where I read this (Noakes or Pfitz)but the reasons given were that if you run the second half faster, you may have held back back too much in the first half to get the the best time possible and if you run the first half too fast you will lose more than you gain in
the second half.
