TGS Extreme

Race strategy

Hold a steady pace and save energy for every section.

• Big early climb with 1850m gain. Hold your pace, save your legs for later.
• 852m descent. Go easy, save your quads.
• Steep 45% wall. Control your pace and stay focused.
• Final 846m descent. Save your legs to go all out on it.
• Control your HR on the first mountain, save your quads on the descents until 31.1km, then run your race pace, and go all out on the final descent from 34.9km.
• 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–15.4km · Climb of 1851m, high point 1794m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
• Work · 15.4km–25.2km · Descent of 852m averaging 15%, climb of 800m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Hike the steepest pitches.
• Fade · 25.2km–34.9km · Descent of 1228m averaging 21%. Plus 2 more climbs and 1 descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 34.9km–40.4km · Descent of 846m averaging 15%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end. Hike the steepest pitches.

Poles

Trekking poles are strongly recommended: about 8.5km of the course is steep enough for them to pay off.

Quad damage

Quad damage risk is moderate (index 40 of 100), with 34% of the load in the first half: 2 descents deserve a plan and a couple of downhill sessions before race day.

• Control your HR on the first mountain, save your quads on the descents until 31.1km, then run your race pace, and go all out on the final descent from 34.9km.
• #1 · 15.4–21.2 km · 852 m D−, -14.8% · 19.2 km ahead → control
• #2 · 25.2–31.1 km · 1228 m D−, -20.7% · 9.3 km ahead → control
• 34.9–40.4 km · 846 m D−, -15.5% · 0.0 km ahead → even, let go at the end
