The Event

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 (formerly Dearnford Lake) in Whitchurch, Shropshire.

If the long distance UK Ultimate Triathlon is not for you then the UK Ultimate 1/2 Triathlon or the Ultimate 1/4 Triathlon may be. 

  • Probably the fastest 'iron distance' in the country
  • Freshwater multi-lap lake swim with Australian exit in between laps
  • Picturesque countryside cycle & run routes, ideal for PB's
  • Swim start, transition & run finish all within a stone's throw of each other
  • Electronic chip timed
  • Fantastic picturesque venue with on-site facilities including showers, parking, camping/caravanning and lakeside cafe
  • Spectator friendly venue, great for supporting friends and family
  • Includes finishers medal and official race T-shirt
