Two full laps of the 25K loop ("the 50k doubles the 25k experience with two full laps of the 25k loop" - swvarunning.com). loop_distance_miles uses the single lap's chart mile (15.8); the race's own chart finish for 50k is 31.1 mi, 0.5 mi under a literal double of 15.8 (31.6) - a small, unremarked rounding gap, not flagged as a conflict. elevation_gain_ft/loss_ft are 2x the single-lap GPX figures, assuming the two laps are elevation-identical as described.

Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
