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.

SWIM – 400m

This is fantastic swimming pool made for swimmers! We’ll have use of 8 lanes which will allow up to 3 swimmers per lane. You will start at the far end of the pool as you look at the photos and after completing the 16 lengths you will exit through the Fire Exit door which is located to the left hand side of the pool as you view the photo.

We will have a counter per lane and they will make it clear to you when you have two lengths to go.

Bike – 23km

The bike course takes you down to Llanstephan . You will mount your bike at the designated Mount Line ( please see Transition map ). You will turn left out of QE High School and head down to Llanstephan. As you cycle into Lanstephan you will turn left towards the Car Park. There will be a dead turn around a traffic bollard before you take the narrow road down to the Car Park. This will be clearly sign posted and marshaled. You will then re-trace your steps back towards the Leisure Centre. You will turn right back into QE High School car park – we hope to have a police officer present to assist but you have to abide by the Highway Code at all times.

Run – 5km

New Run Course :  This is one lap run. When heading out onto the run course you must make sure you race number is facing forwards. You will be directed out through the top of Transition and onto the path which will take you down the Tywi riverside path. You will follow this path alongside the river and towards Carmarthen Town. Once you get to the Quayside in Carmarthen you will move from the path and up towards Tywi Works where you will take a right turn across the old Town’s river bridge and right again towards the railway station. You will then be directed over the new Tywi bridge and back towards the Leisure Ctr.
