Most effective half marathon sessions
Hi all, looking for a bit of advice on effective hard half marathon training sessions.
I have a half marathon in about 6 weeks but I have been doing mainly 5K/10K training (specifically following one of the 10K plans on this site) the last couple of months (after being out with shin pain from October), but I did 2 full marathons last year (3:00, then 2:47) and my best half time was 1:17. My question is as I have only a short period of time left before my big race, so what are the sessions that I should be doing to get the most out of myself? I'm (unrealistically) aiming for sub 1:15.
I know I need to get some threshold training in, but looking for some specific sessions to pencil in next few weeks.
