Heat-Prepared Tom Evans Takes First at UTMB Tenerife Bluetrail 110k

Understanding the thermal demands of the course, Tom committed to a two-week heat training block six weeks before the race. He explained:

“I did an intensive 2-week heat training block 6 weeks before the race – once I had the adaptations, it was easy to maintain. I did 3 heat training sessions per week. I trained outside first, and then when finished I got straight into the turbo trainer or treadmill in my core suit and trained in heat zone 3 for 45–60 mins. This allowed me to train with the quality I needed but also get the heat preparation.”

This combination of outdoor endurance and indoor heat training in his CORE Heat Suit likely helped trigger key physiological adaptations: increased plasma volume, lower resting core temperature, and more efficient sweating—all essential tools in keeping heat strain low under race pressure.

But it wasn’t just pre-race preparation that made the difference – Tom implemented strategic cooling measures throughout the race to keep his heat strain in check. Dumping cold water over his head at aid stations helped prevent overheating during long, exposed sections in the sun-baked lowlands.

With a course that winds through volcanic deserts, pine forests, and high alpine trails – including a summit above 3,500 meters – apparel and correct layering is also a crucial consideration in race-day strategy. From breathable layers designed to shed heat in the scorching early sections, to warm, moisture-wicking insulation for the cold night-time descents, every item must be carefully selected for its purpose. Tom adjusted layers as he moved through vastly different environments, ensuring his body could regulate temperature efficiently without overexerting itself trying to stay warm or cool.

Ultimately, Tom's heat prep and cooling strategies paid off, enabling him to spend only 33 minutes of his entire race in Heat Zone 3 – meaning he avoided performance degradation from heat stress for the vast majority of the race.

Tom’s victory is a case study in the power of deliberate heat adaptation and real-time thermoregulation. For endurance athletes competing in variable or extreme environments, it’s clear: training smart, dressing strategically, and staying cool can be just as important as fitness when it comes to crossing the finish line first.
