Make sense of the conditions
- Dew point, WBGT and running in the heat
Read the heat and humidity before deciding what pace makes sense.
- When drafting helps your running pace
A group can help, but its pace and the conditions still need to suit you.
- Pacing the climbs and descents
Use the course profile to think about effort, not just splits.
Pacing and conditions FAQ
Beyond conditions
Conditions are only part of the race-day loss
