Warm start, warming through the race, chance of rain

Starting at 67°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temperatures rising to 77°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 68% is worth noting for effort level, especially in later miles.

About the Niagara Ultra Races 50K

The 50K is a scenic out-and-back ultra on the paved Niagara River Recreational Trail along the Niagara Parkway. It runs from Niagara-on-the-Lake past historic Fort George, vineyards and wineries to a turnaround near Niagara Falls, where spray from the Falls drifts across the path. The surface is smooth pavement with several road crossings and about 310 metres of total climbing.
