While mud mat be the curse of many an outdoor event, there’s one festival in West Cornwall that is offering as much of the gloopy stuff as anyone can take.

Tuff Enuff, billed as Cornwall’s first endurance obstacle race, has already attracted more than 800 challengers from as far away as Belgium to test their stamina over 12km of mud, sea and man-made barriers.

Tuff Enuff organiser Tony Borrett said: “Although Tuff Enuff is being touted as the most challenging endurance obstacle race in the UK, many entrants are entering for the fun of the event by striving to complete the course rather than compete against some of the best athletes in the game.”

Aside from the spectacle of the races - which has a less strenuous 5km course alongside the gruelling 12km option - there will also be a free daytime entertainments and activities for all the family.

The daytime event, which is free, has live music, trade stands and fitness demonstrations, food stalls, inflatables, a skate ramp and exhibitions from the armed forces.

Tony added: “After the races, and everyone has managed to shower off the layers of mud, we present the evening Apocalypse After Party featuring top live music and bands from 6pm to 3am.”

Such is the demand for the Tuff Enuff challenge, a three-session-a-week boot camp has been put into play. Scores of competitors have embarked on an intense training programme prepared by Simon Raynes, of the Cornish Pirates, which focuses on good technique.

Simon said: “Technique and correct form are much more important in a race like this than multiple reps over a specified time.

These training days are going to be filmed so that people who cannot travel to the boot camps can take advantage of the training techniques.”

Another UK first for Tuff Enuff is the use of satellite link technology to enhance the event.

Cornish networking specialists Microcomms will provide a satellite link at Tuff Enuff that will enable race times to published on the day of the event - a feat not achieved at many obstacle races due to the amount of entrants and the staggered start times.

Local photography firm Photomaze will use the satellite link to upload pictures of competitors online on the day of the event. The link will also provide free wi-fi for to visitors to Tuff Enuff.

Tuff Enuff takes place on Sunday, May 25, at Westmoor Farm, St Buryan, Cornwall TR19 6EX. There are full camping facilities with ample parking.
