Temperatures in °F. National Weather Service forecast for grid MTR/90,138, issued Oct 16, 1:26am PDT. Forecasts change — look again on race morning. We only know the town, not the exact start, so this is for the town's grid square. NWS publishes no WBGT for this spot.
This race is hand-checked. No feed we ingest carries it, so somebody read the organiser's own page and wrote the date down — which is also why it can be out of date in a way the rest of this site cannot. The link goes to the organiser.
