Grindfest is one long progression run originally developed in Milwaukee, Wisconsin in 2013. The race/workout has now been spread all over the world, arriving in Portland in 2019.
The rules are simple - start at either 9 minute mile pace (wave 1) or 8 minute mile pace (wave 2) or 7 minute pace (wave 3) and progress 20 seconds every mile (3 laps to a mile at Benson!). You stay in as long as you can until you can no longer grind the pace down any further and you wave the white flag.
Benson's newly resurfaced track is a one-of-a-kind 4 lane 535 meter track where 3 laps is around 1 mile. It's a beautiful facility that is perfect for grinding out a long progression run.
This year the Portland Grindfest will serve as a fundraiser for Benson Cross Country as we’re raising funds to help cover travel costs for end-of-season meets where runners have the chance to compete against top talent and create lasting memories. Your donation helps provide transportation, lodging, meals, and the opportunity for every athlete to finish the season strong—no matter their financial situation. Thank you for supporting Benson Cross Country!
