As we all pause before the massive weeks ahead, we check in on events in California, Colorado, Canada, and beyond.

Tamalpa Headlands 50k – Muir Beach, California

It was the race’s 27th year, and the prize purse was $10,000. Race winners each earned $2,500, with $1,500 and $1,000 going to the second- and third-place finishers, too.

Spencer Ferguson-Dryden rolled the men’s race and won in 3:50. He was over 10 minutes ahead of second place while improving on last year’s third-place finish. Kevin Stewart and Nick Cioci got on the podium in 4:01 and 4:09.
