Training tips
- 1.Walk every uphill — it's strategy, not weakness
- 2.Start each run slowly — you should be able to hold a conversation
- 3.Trail shoes are mandatory: lugged sole for grip on technical terrain
- 4.Trekking poles are allowed and very useful at this distance
- 5.Hydrate regularly, even if you don't feel thirsty
- 6.Elevation gain (D+) matters more than distance — pace by effort
Frequently Asked Questions
Am I too much of a beginner for a 15k trail?
Not at all! The 15k trail is an ideal entry-level trail format. This plan includes walk/run phases and requires no prior trail experience. If you can walk for an hour without pain, you can prepare for this plan.
Do I have to run the whole distance?
No. In trail running, even elites walk steep uphills. You can and should walk all major climbs. The goal is to finish, not to run 100% of the way.
What minimum gear do I need for a 15k trail?
Trail shoes (lugged sole), weather-appropriate clothing, and a small belt or vest to carry 500ml of water. Check your race rules — some require a mandatory gear list.
