What is a Duathlon?

A duathlon is a an event that brings together running and cycling into one challenge. The format starts with a sprint, before moving onto a cycle section, and then back to a sprint. Before you get started with a duathlon, you’ll need to prepare yourself for both disciplines, becoming a master at running and cycling.

How to train for a duathlon for beginners

Your training for duathlon will be trickier than most, as you have to prepare for two types of sport in one race. You should aim to train at least three times a week to keep yourself on track. You might need to split up your running and cycling sessions, as it can be tricky to plan where you can stop and swap onto the bike. You can find more tips for training here

Know the rules

There’s not too many rules to know about with a duathlon, and the ones you’ll need to pay attention to mostly concern the bike section, or the transitions between the run and cycle sections. Some things to be aware off are:

  • You have to keep your helmet on whenever you’re using the bike. So once you finish the first run, you’ll have to put the helmet on before getting on the bike, and keep it on until you’ve finished the cycle section completely.

  • You have to keep at least three bike lengths between you and the bike in front. If you want to overtake, you’re allowed 15 seconds to get past the person, otherwise you’ll have to fall back to the three lengths again. Riding too close or alongside another cyclist is known as “drafting”, and you can get disqualified for it.

  • There will be marked transition areas between the sections of the race, and there will normally be a transition line before the cycle section, and you mustn’t get on the bike before crossing this line.

Run 1: 9km/325m ascent

After utilising some excellent trails on the east side of the forest last year, Run 1 will be a slightly shortened version of last year's route. This will be the same course but missing out the long section of forest road. The terrain incorporates a great combination of woodland singletrack, wide forest trails, a 'few boggy' sections then a superb rocky bridleway descent back to transition area and onto your bike.....


The mountain bike route is a testing 24km circuit (clockwise) incorporating the full North Face trail with additional sections of undulating forest roads and flowing singletrack. This is a real classic bike route designed to incorporate a balance of terrain that will test riders of all abilities and take in many of the best features of the forest.


Run 2: 6.5km/255m ascent

This will be the same route as in previous editions, climbing up to Carron Crag the highest point in the forest. This is a testing route with 350m ascent Take in the stunning panoramic views before a great descent through the forest to a well deserved finish.


Terrain: Run routes are on a mixture of singletrack & forest roads. The North Face Trail is a Red graded mtb route involving technical singletrack climbing & descending. This is a purpose built trail comprising 9 sections of single-track featuring rocky sections, switchbacks, berms and boardwalks, linked together by forest roads.
