Course Information

Swim Course

The swim takes place in the beautiful H2O Lake, surrounded by trees and sheltered from the wind. The sprint distance swim is a single lap and the Olympic distance swim is a two lap course.

As is to be expected with gravel pit lakes, there is sometimes weed present in the lake. The Swim Centre works hard to keep any weed under control to ensure the swimming experience is as pleasant as possible. We will advise as and when necessary regarding any weed present.

Bike Course – Updated for 2023

The Reading Triathlon bike course takes you through the rural Berkshire roads, with some straight fast stretches and some gentle undulations too.

For the sprint race we have a single loop 22km course, up to Mortimer and back through Grazeley.

The Standard and Aquabike races take you on a 42km route starting along the same route as the Sprint course. At Mortimer we take you out on a lovely route through Silchester, Stratfield Saye & Beech Hill. You then be rewarded with a lung busting climb up Mortimer Hill before turning back on to the Sprint route.

For the 1983 route you will do a lap of the Standard course and then a lap of the Sprint course, to make up to the 40 miles needed for this original challenge.

Most of the bike course is on open roads, but they are largely quiet. Any potholes or hazards will be clearly marked on the road. There is one right turn at Grazeley Green, which is a mandatory foot down.

There is also one set of traffic lights on the bike course on a section of closed road near the end of the bike lap, but participants are permitted to go through the red light here (with care).

Run course – All new for 2023!

This year we have a brand new run route for you! We start with a single lap around the lake, before setting off towards the Kennet & Avon Canal. You’ll run along public footpaths and through fields. Once you arrive at the canal, those running 5km will turn right and run back along the canal before being directed back across open fields towards the hotel.

Those completing either the 10.5km or 21km runs will turn left and complete a longer route, past the Cunning Man pub towards Theale, before turning back and following the same route as the Sprint runners back to the hotel. 1983 participants will get to complete 2 laps of our stunning run route.

All the run routes can be found in the Komoot collection above.
