haha after about 1 mile of my LSR today i thought 'bugger, i didn't apply the vaseline' .... carried on regardless, it was ok - but for me it's usually afterwards i notice the unpleasant results 
i do gels. gets quite expensive! lucozade gels are ideal for me, a quick gulp and washed down with water the taste is gone. i can't drink the lucozade pouches. howey i hear there are gel stations at london this year? (don't think they had them in 2007). so perhaps worth a try? i couldn't run without them, it helps break up my run.
good splits Daren F, I think I could have run something very similar today, but it didn't quite work out that way. no real issues though:
9.08, 8.48, 8.54, 9.17, 9.17, 8.54, 9.20, 9.05, 9.25, 9.04, 8.47, 8.01, 8.01, 7.49, 7.39, 7.43, 7.50, 7.57, 8.04, 8.35, 9.26, 9.28
knackered by the end but pretty pleased with how it went. had intended to do 8m/m right up to the last mile but couldn't quite get there. and i couldn't work out how i ran so slow (relatively) in mile 4 and 5. i looked down at the garmin and couldn't believe it! but this is just a sign of how far i've come and how much i've raised the bar.
overall, pleased to be back and the thoughts of peaking too early are put to rest. i think 8m/m will be tough to maintain though. and it may just come down to the conditions on the day. bring it on.
