Intro

Lee Grantham’s “Mastering the Unknown: Training for a Race That’s Nothing Like Home” looks at preparing when the course is different from your home terrain. The main takeaways and a workout are below. Watch the full video for more.

Key points

  • Match training to the race’s terrain (average gradient about 6.5%, up to 10% on the steepest stretches), even if you live somewhere flat at sea level.
  • Treadmills are useful for course simulation. Set the incline to match the race, start with longer slower uphill efforts, then progress to quicker paces and intervals.
  • Build an uphill fitness base before adding speed work. Tendons, ligaments, and muscles need conditioning for steep inclines.
  • Account for heat and altitude. In warm conditions, expect higher heart rates and slower pace. Plan nutrition with that in mind (e.g., a gel every 40 minutes).

Workout example

Treadmill uphill training (km)

  • Sunday long run: 60 minutes at 6.5% incline, starting at 6 min/km (10 km/h). Extend duration as you get comfortable.
  • Wednesday intervals: 6-10% incline. 8 x 3 minutes hard (5:30-5:45 min/km) with 2 minutes recovery on flat. Adjust reps and duration as fitness improves.
  • Easy runs through the week: easy and flat (trail or road) to keep the aerobic base.
  • Fueling: 25 g carb gels every 40 minutes on long efforts. In heat, lift water and electrolytes, or add fresh fruit and watermelon.
