Distance: Half marathon (21.1km)
Target pace: 4:59 per km
Our Sub 1 hour 45 half marathon training plan is over 12 weeks and is completely free to use.
You can decide if you want to do all 12 weeks or start at any point during the training plan, it's completely up to you.
Awesome, you've chosen a plan that should give you a tough but rewarding challenge. A half-marathon at this pace requires the perfect balance of working on speed but also getting a lot of miles under your belt, and this plan reflects that. Aim to get as many of the mid-week speed sessions done and also carve out a couple of hours at the weekend for a nice slow long run. We've added more timed long runs than normal so you can keep tabs on your progress towards hitting your target pace after the 12 weeks.As always, those easy days can be replaced with some lower impact or strength work, alternatively recharge with some yoga or a full rest day.
