Overview

The Speyside Way Ultra 100km, organised by Moray Way Ultras, is a trail race starting in Aviemore, United Kingdom, in August. The 100km course features 4080m of elevation gain, which translates to 40.8m of climb for each kilometre. This makes it a more challenging course than the average 100km race.

With 13 finishers in 2023, this race has a smaller field than 24% of its 100km peers. The 18-hour time limit means runners must maintain a pace faster than 10.8 minutes per kilometre, a cutoff tighter than 36% of 100km races. The entry fee ranges from £73 to £75.
