Ultra Trail Chianti Castles

Race strategy

Hold a steady pace and save energy for every section.

• The finish is runnable. Save your legs to run it all the way.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, then run your race pace.
• Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.7km–51.3km · Plus 1 more climb. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
• Work · 51.3km–62.1km · This is where the race is built: steady, solid effort. Running pays off here: run wherever you can.
• Fade · 62.1km–116km · 5.9km of runnable trail, high point 900m. Plus 2 more climbs and 2 descents. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 116km–121km · 5.3km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
