What you need to know about Duathlon

Duathlons were primarily created to allow triathletes to race during the winter months without the need to swim in cold lakes. It’s a running and cycling event that has become very popular in recent years, they’re great training races for triathlon and make an excellent step up from single running/cycling events. So, if you want to broaden your horizons and move into multi-disciplinary events, Duathlon is an excellent place to start.

Duathlons tend to follow the same distance structure as triathlons, although the format is typically ‘Run—Bike—Run’ meaning you start with a run, then transition to the bike, then transition back to running again. Duathlons come in Sprint, Standard and Long distances.

Different Duathlon event types

  • Sprint Duathlon: 5km run, 20km bike, 2.5km run
  • Standard Distance Duathlon: 10km run, 40km bike, 5km run
  • Long Distance Duathlon: 10km run, 150km bike, 30km run

These distances aren’t as standardised as Triathlons, so do check the exact course. Duathlon races can cover all terrains with opportunities to run cross country and mountain bike. We’ve curated some of our favourites below, good luck out there!

Welcome to the Turkey Tri. Come out and BURN those holiday calories with triathlon distances challenging enough for the seasoned triathlete, yet short enough for the novice triathlete. The event begins with a fun filled mile, calm, lake swim. The bike is a 14 mile (2-loop) road course that is mostly flat with a couple of small hills. The run is 4.5 miles all on paved surfaces around the lake. Everyone gets a piece of Pumpkin Pie at the finish line!
