About ChekkPoint
Every checkpoint, accounted for.
ChekkPoint is an open, offline-first endurance race timing and athlete intelligence platform built for mountain ultras, backyard loops, gravity MTB, and regularity rallies.
Multi-Split Dwell & Time Allowance Rigor
Inspired by OpenSplitTime's gold-standard endurance data model: separating physical TimingPoints from logical CourseSplits, tracking IN/OUT aid station dwell times, and deducting official medical/weather TimeAllowances.
Zero-Signal Backcountry Capture & Radio Sync
Rooted in TRacer's amateur radio checkpoint operations: decoupled FIFO chute entry, Damerau-Levenshtein bib typo defense, local IndexedDB/OPFS persistence, and acoustic MT63 VHF/UHF packet transmission.
Calm Cartographic Clarity Under Pressure
Designed like a printed USGS trail map rather than a noisy telemetry cockpit—warm paper surfaces, fine contour lines, EB Garamond serif numerals, and strict tabular alignment.
Explore the Platform
Built for every role on the mountain.
Whether you are directing a 100-mile mountain ultra, logging bibs at a windy ridge tent, or pacing a runner through the night, explore our dedicated guides and live directories.
