10-Week Intermediate Half Marathon Training Plan
Shooting for a sub-1hr 45min half marathon? Step this way for the perfect training plan
Target time: Sub-1hr 45min
Race pace: 8min/mile (5min/km)
This plan is for you if: You run regularly, have finished half marathons and want to shoot for a sub-1hr 45min PB.
This ten-week plan from Soar running coach Ben Noad will put you in the best possible position to run a half marathon in 1hr 45min or less. There are five sessions a week – a mix of intervals, tempo runs and long runs.
There are two options for each training day. The first is the recommended session if you’re in tip-top shape, and the second is a back-up plan if you’re short on time or feeling especially tired. Noad has also provided coaching pointers throughout.
The plan uses “Soar paces” to explain how fast to run in each session. These range from Soar pace 1, which is a comfortable relaxed pace where you can hold a conversation with ease, to Soar pace 5, which is a sprinting pace that you can only sustain for two minutes or so.
In between you have gradual increases in intensity. So Soar pace 2 is faster than 1, but still a pace you can hold for long periods comfortably. Soar pace 3 will be around your half marathon or marathon effort, in that it can be held for long periods but you are working quite hard. Soar pace 4 is faster still – around the effort level you’d put in when running a 5K or 10K race, so pretty tough going even in fairly short bursts.

Your five Soar paces should be personal and reflect your fitness level, and they can also change from day to day depending on how fatigued you are or the terrain you’re running on. It’s about the effort level rather than speed – there’s no point in overdoing it to smash your easy Monday session if it leaves you with nothing in the tank for the rest of the week.

Coaching points: Try to use an out-and-back course for the intervals so you start in the same place for the odd and even number reps. The key to all interval sessions is to remain consistent – you want to be finishing the session stronger than when you started. Think about your pace and whether you can hold it for the entire session. Remember the benefit of the session comes in the second half so try to manage your effort accordingly.
