Alberta ultrarunners set new Sinister 7 course records

Women achieved outstanding results in both the 100-mile and 50-mile distances

The Sinister 7 ultra-marathon returned to the mountains of Alberta Sunday, and local runners Kevin Biggs and Ailsa MacDonald were the men’s and women’s winners, and the first two across the finish line of the grueling 100-mile race, setting new course records in both the men’s and women’s categories.

The women’s race

Not only did MacDonald win the women’s race by nearly seven hours, she also finished second overall, only 14 minutes behind Biggs, in 18:19:42, taking 35 minutes off her own course record. MacDonald is very experienced in the world of ultra trail racing, and is an established trail runner, ultra runner, road runner and triathlete. In 2017 she claimed the 50K and 100 mile Canadian National Champion title, in 2018 she won Ironman Canada and in 2019 she won the Pemberton 50K in Arizona overall and set the course record. MacDonald owns multiple course records and two overall wins at the ultrarunning distance. Second place went to Jennifer St Pierre in 24:54:11, and Faye Baldock took third in 26:54:07.

The men’s race

Biggs is a relative newcomer to the sport, and according to Ultrasignup.com, this is only his third official ultramarathon. His time of 18:05:43 took three minutes off Scott Cooper’s previous course record, set in 2019. Alberta’s Dave Proctor, who owns several Canadian ultrarunning records, was the second male across the line (and third overall), in 21:15:31. Third place went to Calgary’s Shaun Parker, who finished in 22:12:34.

50-mile results


The women showed spectacular results in the 50-mile also, with Calgary’s Arden Young in a sprint finish with Jazmine Lowther, who finished second and third overall, Young in 8:39:13 and Lowther in 8:39:27. Chelsey Topping was third female and 10th overall, in 9:59:33.

On the men’s side, Dave Stevens of Nelson, B.C., took the win in 7:56:59. Brad Buxton of Calgary finished second, in 8:43:39 (fourth overall), and third place went to Reinier Paauwe in 8:44:22 (fifth overall).
