Solenne Billouin, Arthur Serrières win XTERRA Czech Short Track Solenne Billouin (FRA) and Arthur Serrières (FRA) captured the XTERRA Czech Short Track off-road triathlon titles on a beautiful blue sky day at Ktišský Lake on Sunday, August 13, 2023. The action-packed event was the seventh of 12 points-scoring races and the third of five XTERRA Short Track races in the XTERRA World Cup. It combined a two-lap 400-meter swim, with a four-loop 7.6-kilometer mountain bike, and a two-lap 4K trail run. Billouin won it in 38 minutes, 35 seconds, Serrières in 32:42, and both were awarded prize money and 20 points for their efforts. For Billouin, the reigning XTERRA World Champion, it’s her first-ever Short Track win and marked a clean sweep for the weekend after winning the full-distance race yesterday, and for Serrières, it’s his fourth career Short Track win and second this season.
