Calculators built for the long miles.
Three working calculators today, with two more on the way. Numbers that respect the kilometers you've already put in. No email-gates, no upsells, just math the general-running sites don't bother with.

Vert Calculator
Enter your distance, total elevation gain, and a goal flat pace, get an honest finish time, vert-per-mile, and an equivalent flat-mile pace.
- № 02 →
Drop-Bag Planner
Race distance, drop-bag count, weather, night running. We print a per-bag checklist with calories, hydration, layers, and the small things that quietly save hundred-milers.

Ultra-Pace Calculator
Take your marathon time, factor in your race distance and vert. Output is a realistic finish-time estimate, average pace, and slowdown vs marathon.

Splits Calculator
Punch in race distance, vert, goal finish time. We print honest per-aid-station splits with distance fade and climb penalty baked in.
