Build my planGet ready for another CAL CRUSHER 2026 - ENDURANCE RUN!! Come on out and crush as many miles as you can in 30 hours. Just so we are on the same page...this is a FUN RUN.
This year's race donations will go towards the research for Breast Cancer at the Van Andel Institute. "Van Andel Institute engages the world's brightest minds and advances the boldest ideas in pursuit of the biggest breakthroughs for humanity." Breast cancer has impacted many people either directly or indirectly. It is a cancer experienced by both men and women. Come on out, wear pink, support the research, and crush some miles in honor of someone you know that has fought a battle with breast cancer.
Like last year, run/walk all your miles at once, or run - go home and sleep - come back and run some more, or for those that have never run through the night and want to just see what it's like, make it a midnight run adventure. It's all up to you!! Again, you will have 30 hours to crush as many miles as you can. Awards will be given out for the male and female who crush the most miles in 30 hours. Miles will be tracked at the aid station. Running time will start at 6:00 am on Saturday, October 24th. Clock stops at 12:00 noon on Sunday, October 25th. The race will begin and end near the pavilion of the Caledonia Community Green Space. There will be an aid station as well as restrooms available. The route will be a 5 mile loop through Caledonia, on the trails, and around the schools.
Cost: $35 per runner which includes a shirt, aid station snacks, water/juice, access to restrooms, award for both Male and Female “most miles crushed”.
If there are questions prior to race day, feel free to reach out to me.
*** UPDATE *** I will be ordering shirts on October 8th to ensure they will be here on time for the Cal Crusher on October 24th. Anyone signing up after that date is subject to availability.
