To coincide with the final rest day at Le Tour 2026, Rachel Jary sits down to speak with Aline Barre, CORE's Endurance Performance Lead, about what heat training actually is and why it's become essential to rider performance. Aline works with WorldTour teams and elite triathletes, and holds a master's degree in sports performance analysis, as well as being invested in endurance sport herself.

And with global temperatures climbing every year, a CORE sensor is fast becoming standard kit for serious riders. To celebrate the Tour, CORE is giving listeners 10% off, so you can train like the pros. Head to corebodytemp.com and use code TDF10CORE. We repeat, that's TDF10CORE at corebodytemp.com.
