IRONMAN 70.3 Bolton Bolton, United Kingdom   Jun 7, 2026

This is Proper Racing
It’s time to have the real British race experience of proper racing! Take in the beautiful bike course scenery, and impressive finish line in the heart of Bolton Town centre where the crowd support is like nowhere else in the world.

Swim
The one-loop 1.2-mile (1.9km) Roka swim course returns to Pennington Flash Country Park, where athletes head out, make two left turns and make their way back to exit the water. They will pass through the noisy crowds on the bank of the lake as they make the short run to transition.

Bike
The 56-mile (90km) bike course, starts with two-loops through the villages of Lowton, Abram and Bickershaw before heading north towards Bolton on roads that will be familiar to those who have participated in previous IRONMAN UK races. The second half of the course sees two loops of Horwich and Bolton which expects to see some epic spectator support along Chorley New Road. An out-and-back section on Victoria Road and Old Kiln Road provides the main climb of the day on a course limited to 840m of ascent with ample opportunity to drop onto the tribars and keep the speed high. After completing the loop of central Bolton for a second time, the bike course concludes at T2 in Queens Park.

Run
The two-loop 13.1-mile (21.1km) HOKA run course laps around Bolton Town Centre before ascending through the scenic Queen’s Park onto Chorley New Road. After descending back through Queen’s Park, athletes will then return to crowds and historic buildings of central Bolton before hitting the iconic IRONMAN 70.3 finish line in front of Bolton Town Hall.
