Running an Ultra Challenge is a huge adventure. Training will help you build stamina, pace, and confidence.
But remember, it’s not just about miles on your feet - running is also a brilliant way to clear your head, manage stress, and connect with others. And we're here every step of the way to get you ready!
Running big distances can feel daunting, but the secret is building up gradually and consistently.
Mix your runs - easy pace, some speed or hills, one long run.
Rest matters - recovery days are where your body gets stronger.
Practice the event style - try run-walk pacing, night running (for 100k), and using your event kit.
A balanced week might look like:
2–3 runs (a mix of easy pace, tempo, or hills)
1 long run (building in distance each week)
1 cross-training or strength session (core, legs, balance)
Top Tip: Training with a buddy or club can keep you going on days when you need a little pick-me-up!
20 weeks out: Start running 3× per week. Break in your footwear and start building a habit.
12 weeks out: Long run around 30km, working on steady pacing.
6 weeks out: Longer runs of at least 40 - 45km. Practice with full kit and race-day snacks.
4 weeks out: Two consecutive long days (e.g. 30km + 20km).
5 days out: Ease back - recovery runs only, light mobility, plenty of carbs.
12 weeks out: Run twice a week minimum, with 1 long run of 15km.
6 weeks out: Long run of 25km, practice fueling on the go.
4 weeks out: Back-to-back runs (e.g. 20km + 15km)
2 weeks out: One 30–35km run, then start to taper.
5 days out: Keep runs short, focus on rest, hydration and carbs.
12 weeks out: Get into routine with 2 runs a week.
6 weeks out: Run 10–12km comfortably,
4 weeks out: Back-to-back 10km runs, test socks and kit.
2 weeks out: 15–20km run, final kit check.
5 days out: Light runs, stretch, relax.
1. Invest in some good trail running shoes. They really do make a huge difference.
2. Find a time that works for you. Life is busy, but training properly is key. Why not wake up an hour early or use your lunch break to get your runs in?
3. Focus on strength, too. Building up core and length strength is key to running far. Aim for once a week.
4. Train your brain, too. An Ultra Challenge is as much a mental challenge as a physical one. Stay positive, set mini goals on your walk, and remind yourself why you're doing it.
