Your first half marathon: how to actually make it to the start line

You’ve signed up. Or you’re about to. 21.1 kilometres, a medal, and a story for the rest of your life. Also: three months of training that has to fit around work, weather and everything else.

Here’s the honest part nobody puts on the race poster: getting to the start line healthy and ready is the real challenge. Race day is the reward.

Why people don’t make it to the start line

• Injuries. New runners get injured more often than experienced ones. A review of 13 studies (Videbæk and colleagues, 2015) found about 18 injuries per 1,000 hours of running for novice runners, against about 8 for recreational runners.
• Life. A busy month, a cold, a holiday, and suddenly the plan is three weeks behind.
• The long middle. Week one is exciting and race week is thrilling. Weeks five to nine are just… long. (We wrote about why the middle of a goal is the hardest part.)

Build up gradually, but don’t worship the 10% rule

You’ve probably heard: never increase your weekly distance by more than 10%. It’s sensible, but it’s not magic. In a Dutch randomised trial with novice runners (Buist and colleagues, 2008), a slow programme built on the 10% rule led to about the same injury rate, around 20%, as a faster standard programme.

On the other hand, in a Danish study of 874 new runners (Nielsen and colleagues, 2014), those who increased their weekly distance by more than 30% over two weeks seemed more vulnerable to certain overuse injuries, although that difference wasn’t statistically clear.

The takeaway: avoid big jumps, increase step by step, and take what your body tells you seriously. No rule replaces paying attention.

A simple training structure

• Three runs a week is enough for most first-timers: one easy run, one with some faster parts, and one long run that slowly grows.
• Most runs should be easy. Easy means you could hold a conversation. If you can only gasp single words, slow down.
• Every third or fourth week, run less to let your body catch up.
• The longest run usually tops out somewhere between 16 and 19 km, two to three weeks before the race.
• The last week or two, cut back so you arrive fresh, not tired.
• Practise race day on your long runs: the shoes, the breakfast, the drinks, the start time.

If you’re not yet running 5 km comfortably, start there first. Your future knees will thank you.

5 things that get you to the start line

1. Pick a race and sign up

A date makes it real. “Sometime next year” never builds a training plan. Choose a race 12 to 16 weeks away (more if you’re newer to running), sign up, and tell people.

2. Put the runs in your calendar

Three fixed slots a week, like appointments. The long run gets a regular morning; everything else gets planned around it, not the other way round.

3. Track it simply

Write down every run: distance, how it felt, anything that hurt. It shows your progress on the days you doubt it, and warns you early when something’s off. Our guide to tracking your progress includes a free 12-week tracker to print, which happens to be the perfect length.

4. Pain isn’t part of the plan

Tired legs are normal. Pain that gets worse while you run, changes how you run, or is still there the next day isn’t. Take a few days off and, if it doesn’t clear up, see a physio or doctor. A week of rest is cheaper than a missed race.

5. Train with someone

The Sunday long run is so much easier to skip alone. With a partner, it becomes a standing date, and the kilometres pass while you talk. In lab studies on the Köhler effect (Feltz, Kerr and Irwin, 2011), people kept exercising longer next to a slightly stronger partner than on their own. Read more on why a workout buddy helps.

Find your running partner

Pactful pairs you by hand with someone who has a similar goal and pace of life, ideally close by. We’re starting in Hamburg, Amsterdam, Rotterdam, The Hague and Utrecht. Maybe they’re training for the same race. Maybe they’re just as stubborn about Sunday mornings as you are.

Join the waitlist. See you at the finish.
