A city triathlete is set to rediscover his youth when he takes on a challenge with a difference to raise funds in memory of a former colleague.

Richard Evans, from Lakenham, is due to take part in the Brutal Extreme Triathlon in Snowdonia, Wales.

The event, on September 22, will see him swim 1.2 miles, cycle 56 miles over two mountain passes and run 13 miles, including climbing up and down Snowdon, the highest mountain in Wales.

The 44-year-old Broads Authority ranger will be taking part in the event to raise funds for the Luke Day Fund.

Set up in memory of the Costessey High teacher who died while on his honeymoon in Egypt with his wife Sophie, the charity aims to help under-18s to access outdoor, cultural and musical opportunities they would otherwise not be able to participate in.

Mr Evans, who used to work with Mr Day at Charles Burrell High School, now known as Thetford Academy, said: 'I grew up in Snowdonia so I will be going back there, having spent the last 14 years in Norfolk, and will be reliving my youth.

'It will be nice to go back to Snowdonia fitter than when I left.'

The member of Norwich-based triathlon club Tri-Anglia first got into triathlons through Mr Day's wife Sophie. He first took part in a duathlon – run, bike, run – with Mrs Day in Thetford 18 months ago, and his passion for events and multi-sport races has continued ever since.

In training for the Brutal Extreme Triathlon, he has been swimming in the open water, cycling long distances, running and doing boxing training with Jackson Williams at Norfolk Tower.

Ahead of the event, he will be taking part in the North Norfolk Triathlon in Wells this weekend and the Anglesey Sandman Triathlon, also in Wales, on September 16, which will see him complete a 1,000m sea swim, a 60km cycle and a 10km run along forest trails, sand dunes and the beach.

Mr Evans, who used to be a mountain leader in Snowdonia, added: 'I think it will be slightly harder than a triathlon but I will have an advantage because I know the area really well.

'It will be the biggest challenge of the year, definitely.'
