Hawaiʻi Bird Conservation Marathon

December 20, 2026Marathon30 m

We start near 1,228 meters at Volcano Golf Course and lose roughly 1,114 meters before Keaau, which makes this fast on paper and brutal on quads. A headlamp is required through civil twilight, rain is likely, and temperatures can swing from about 13 to 26 degrees across the descent. The estimated $120 entry supports native-bird conservation, but the rural point-to-point logistics make this a harder partner weekend than a resort race.

Better info coming — we're still verifying 2 fields on this race.

Why we'd pick it

  • Flat and fast: 30 m of total climb, so it's a genuine PR course.
  • Open · Direct entry — no lottery to lose.
  • Thin on non-race things to do for a partner (2/5).
  • Race day usually sits 13.2–18.7°C, about 54% chance of rain.

The course

The certified point-to-point starts at Volcano Golf Course around 1,228 meters, passes through the Volcano subdivision and onto Highway 11 beside Hawaiʻi Volcanoes National Park, then descends to Herbert Shipman Park in Keaʻau at roughly 114 meters. Almost 1,114 meters of net drop makes it fast but brutal on quads. Rain, darkness at the 6 a.m. start, and temperature change complicate pacing.
