The UK Ultimate Triathlon is like it says, the ultimate triathlon challenge. This demanding and much sought after 'iron distance' event will return yet again to the beautiful Alderford Lake venue in Whitchurch, Shropshire.

The UK Ultimate 1/2 Triathlon is our demanding and much sought after 'half iron distance' event and returning yet again to the beautiful Alderford Lake venue in Whitchurch, Shropshire.

Are you looking to step up from a Super Sprint or Sprint triathlon without a daunting Olympic distance swim? Then we have just the thing. We launched the UK Ultimate 1/4 as a precursor to our 'iron-distance' Ultimate Half Triathlon.

For those of you who find the 1500m Olympic swim a daunting prospect this event offers a fantastic challenge upgrade with just a 0.6mile swim (965m). The event covers one lap of the swim, one lap of the bike and two laps of the run course taken on by the Ultimate 1/2 competitors.

Back by popular demand is the Sprint distance at the peaceful & scenic venue of Alderford Lake where we have been holding events for six years now.

Take on the challenge of swim, bike and run aimed at all abilities from complete novice to club and pro triathlete, as well as charity and fun competitors, with a fun & friendly atmosphere and great support from the cheering crowds.

C-19 Plan
UK Triathlon has confirmed that this event will be going ahead as planned on Saturday 15th Aug 2020 in accordance with the COVID-19 safety measures. Learn more

Community Volunteer Scheme
How to be involved
We offer a Community Volunteer Scheme, whereby one free* race place up to the value of an Olympic distance entry is given in return for a day’s marshaling at any one of the UK Triathlon series of events. This role can be undertaken by yourself (the competitor), a friend or family member who would like to support you.

*The ‘Community Volunteer Scheme’ entry fee has a value of up to the cost of an Olympic distance entry meaning that most of the race places are free.

Requirement and responsibilities
All volunteers have one key role during the triathlon and that is to cheer on and encourage competitors during their special day. In addition to this volunteers can be involved in any one of roles below:

Feed Station
Swim course volunteer
Bike Course volunteer
Run Course Volunteer
Transition area
Finish line area
We typically ask volunteers to arrive around 7/8am on the day they are helping out, for a briefing and breakfast, with an aim to be finished by 3/4pm (this can be earlier depending on event /circumstance).

All volunteers are provided with food and drink to make sure they are fully prepared for their fun and enjoyable day ahead.

Volunteer as a Group

Whether a local sports club, charity organisation, community group or group of friends we would love your help and commitment to come along and join us at any of our races across the UK.

Over 90% of the UK Triathlon race crew are volunteers, many of them have been with us for over 15 years and without their support and dedication, these events would not run.

4.5 out of 5 stars

  • Course
  • Organisation
  • Atmosphere
  • Did the Ultimate Triathlon in 2020

    Chose this as my first long distance event for a number of reasons; 1 hour away, internet reviews, 220 mag reviews, personal reviews from Oldbury STC club members. The right decision! Great course that you can practice fully in advance. Swim is better than it looks, cycle is a great mixture of quiet country lanes, quiet long main roads and a short busy dual carriageway. Vic the organiser is very helpful and friendly. The bike motivators on the run course spent a little time with all motivating us. The girls at the feed stations were totally inspirational and fun (especially the 3 outside venue. Almost all competitors on 6 lap run were encouraging each other as were the marshals and supporter. Not the huge razzmatazz and atmosphere of Ironman Wales but perfect in so many other ways. Strongly recommend!
