The 2015 London Triathlon saw Klober managing director David Arendell and technical manager Graham Copson compete as part of the SIG Roofing Racers team to raise money for charity.

The Klober employees acquitted themselves well, generating over £1,000 of sponsorship money in the process for McMillan Cancer Support and Great Ormond Street Hospital.

The SIG Roofing Racers team each year brings together members of the Roofing, Roofline and Windows industry.

Despite a flat tyre on his bike Mr Copson came in just 10 minutes after his colleague, who completed the course in a little over 1 hour 50 minutes.

Mr Arendell said: “Temperatures weren’t actually as bad as previous years though the run is always a killer at the end”.

SIG has already indicated its desire to field a team again in 2016. Both of Klober’s 2015 competitors have declared themselves ready for next year's challenge, the company says.
