FAQ
Questions, answered
Keep it simple.
Isn’t this the same as free race planners?
Free tools help you plan. TrailBook ships race-day execution deliverables: PacePro sync, fueling snapshots, and printable tactical guides.
How accurate is the ETA?
It’s a decision aid, not a guarantee. It’s based on transparent assumptions (pace + elevation cost + rest). You can adjust coefficients to match your running style.
Do you support ultra distances?
Yes — the output scales. From short trail races to 100-mile ultras, we focus on the decision-making data you need.
Is this official for UTMB / Western States / Hardrock?
No. Open courses are unofficial simulations for education and planning. TrailBook.run is not affiliated with any race organization.
