Training plan built after strong training for a marathon. Aim is to train for 17 weeks to the half marathon, but because of the marathon base, there isn't a build up in distance (I was already doing more km than this plan calls for). Only use this plan if you already have a good base. Paces do increase over the duration of the training plan, increasing from around 5:45/km to 5:15/km for the easy runs, with a target of 4:30/km on race day (1:35 finish time).
