Vaca Backyard Ultra
We hold no course length for this race — a timed or backyard event is measured by the clock, not the kilometre — so there is no Grit score to give you.
What the course asks
DUV results for the 2025 edition (24h) — ranked runners only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, October
Regional 2001-2020 average for October — NASA POWER, grid elevation 38 m. Not a forecast.
