Event overview

Fun, friendly and relaxed with friendly marshalls and plenty of crew around to encourage and support the participants.

Choose from two distances with mechanical and medical support, as well as the cheer of the spectators.

The cut off times are extremely generous. We want to see as many people finish and achieve their goals as possible, all while ensuring everyone receives the same experience from the event team.

Swim

Swim in the shallow and clear open water man-made lake within Allerthrope Lakeland Park. The water depth is no more than 5ft, giving entrants the option to stand if needed. This venue is also well sheltered from winds, meaning the water is flat and not choppy.

Cycle

The bike portion of this race has triathletes take on a flat and potentially fast open road course around the quiet country lanes of the park and local villages.

Run

The picturesque flat trail course around the lake creates a spectator friendly route to keep you going when you need it most. With a closed road section to keep you running safe and enjoy the experience.

This event is part of Sundowner Triathlon.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
