Hackney Half training plan: 12 weeks from beginner to finish line

Hackney Half is one of London’s best-loved races. Flat, fast, atmospheric, and pitched perfectly at the gap between casual parkrunner and serious club runner. It is genuinely a brilliant first half marathon. It is also 13.1 miles, which is roughly 21 kilometres, and that is a real distance that requires real training. Showing up undertrained and trying to wing it is the recipe for either injury or a miserable race.

If you are coming from a 5K or 10K base, 12 weeks is the right window. You have time to build the mileage gradually, do the long runs that matter, and arrive at the start line ready. If you are coming from absolute zero, 12 weeks is tight but still possible if you commit to it. This plan is built for either, with progressive weekly targets and clear key sessions.

Here is the complete 12 week plan with an interactive tracker so you can see exactly where you are and what is coming.

The three principles this plan is built on

1. Most runs are easy

Around 80 percent of your weekly running should be at easy, conversational pace. This builds aerobic capacity without overcooking your legs. The temptation to push every session is the single biggest cause of beginner injury and burnout in half marathon training. If you cannot speak in full sentences during your easy runs, you are running too fast.

2. The long run is sacred

The Sunday long run is the most important session of your week. It is the one that teaches your body to run for the distance. Build it gradually, do not skip it, and run it at easy pace. Forget about speed on the long run, the goal is time on your feet.

3. Strength keeps you healthy

Two short strength sessions per week, including squats, lunges, glute bridges, and core work, reduces running injury risk by around 66 percent according to the 2018 BJSM meta-analysis. This is not optional in half marathon training. It is what keeps you on the start line.

The runners who finish strong at Hackney Half are not the ones who trained hardest. They are the ones who trained smartest and most consistently for 12 weeks.

The Hackney Half course specifically

Hackney Half is genuinely beginner-friendly as halves go. The course is flat with only minor undulations through Victoria Park. There are no surprise hills, no exposed wind tunnels, and the route through east London is well supported with cheering spectators that make hard miles feel easier.

The race typically takes place in May, which means your 12 week build sits across the late winter and spring. Plan for cold, wet long runs in February and March, warmer ones in April. Invest in a proper waterproof jacket and merino base layer. The training will happen in conditions you do not love. The race itself will, with luck, be in beautiful east London May sunshine.

Race week and the 24 hours before

The final week, the taper, exists so your body can absorb the work and arrive fresh. Cut your mileage by roughly 50 percent from week 10. Do not do anything new. Sleep more than usual. Eat slightly more carbohydrate than usual in the final 2 to 3 days.

The night before Hackney Half, lay out your race kit, pin your race number on your top, pack your gels or fuel, set two alarms, and try to be in bed by 10pm. Race morning: porridge or toast with jam roughly 2 to 3 hours before the start. Coffee if that is your routine. Get to the start line 45 minutes before your wave to allow for toilet queues and warm-up.

How Edge handles half marathon training

The plan above is a generic 12 week structure. The challenge for most runners is that real life does not follow a generic plan. Holidays come up. Work explodes. Sessions get missed. The plan has to adapt or it gets abandoned.

Edge’s half marathon plan starts from this 12 week structure and then adapts continuously. If you miss Tuesday’s tempo, the plan reshuffles your week so you do not lose the long run. If your easy pace is faster than the generic plan assumed, the targets recalibrate. The strength and mobility sessions are pre-built into the plan rather than something you have to add yourself.

The result is that you arrive at the Hackney start line with the training done, rather than having either undertrained because life got in the way or overtrained trying to catch up. Over 11,500 UK users now train this way, including a large group of first-time half marathoners.
