STROUD teenager Jack Powis marked his Great Britain debut with a top ten finish in a highly competitive under 20s World Championship triathlon race in Lausanne, Switzerland.

Jack,18, finished in ninth and first GB on a challenging course in what was his first ever international race.

After a choppy 1500m swim in Lake Geneva, Jack managed to work his way up through the places on the bike, which included some steep ascents and technical downhill sections. On the run, Jack continued to pick off his competitors with a strong run in very warm conditions.

He said: “I am pleased with my performance. I found the swim challenging with it being a non-wetsuit swim in unexpectedly rough conditions. However, once on the bike, I felt strong and I enjoyed the steep climbs on the course. I began to hurt on the run, which was one of the hilliest I’ve done in a triathlon, but I really enjoyed the experience and am happy with a top 10 finish.

" Many thanks to my coach Chris Frapwell, and to ‘Gel Engineering’ for their sponsorship. I look forward to building towards the 2020 World Championships in Edmonton and I will be striving to do even better than this year.”
