Third session with Lara at LA Fitness. Stretches, rowing sprints, running sprints, lunges, functional training, and just for a novelty, push-ups. I actually never knew it was possible to sweat that much in an hour – I keep dripping all the way back to work, despite a cold shower.

Carry on mailing out emails to people for sponsorship; today I did E, F, G, H, and I in my address book. If that’s you, you know what to do, loves. Check kit for Sunday. Eat a shedload of carbs. Sober bedtime. Realise that endurance running has basically taken over my life – pretty much everything I have done today has been directly related to it.
