Notessuper tired, but slept like crap. was up early enoguh that i decided to just do my full planned pre-hackney routine (bicarb 2 hours before, 100mg caffeine gel 30 mins before). Looks like that paid off. The warm up jog felt crap, HR in 140s for like 6:1x pace. Race started and 3:38-42 Ks were feeling easy. Watch has it at 5.12k (friends who did it also had between 5.05-5.1). Means it's a little tricky to work out splits exactly, but roughly:
3:42, 3:38, 3:36, 3:46, 3:40 + 21s @ 3:10 pace. Matches the feeling, with 4th k being tough but having enough left to bring it back for the last k and then kick on the final straight.
The weekend before my last half, I ran 19:42 at what was probably a short course and one that iirc is typically rated 'faster' by the parkrun course metrics, which VDOTs to 1:30:29, which is basically exactly what I ran. Today's VDOTs to 1:25:59

bicard less helpful for a half than a 5k so not sure i'll convert the same, but then my training is a lot more specific to half than 5k, so maybe maybe. Anyway, exciting times!
also glad to finally tick off that old 19:16 PR and by a big margin
eta: pretty sure this also featured mile (5:48) and 1k (3:35) PRs, since the strava best efforts for those look pretty borked
