Black River Trail Classic 25k

October 21, 2017

General Info

Thanks for checking out the Black River Trail Classic! We're really excited to have a trail running event in the Black River State Forest. The forest is already known for its cross country skiing and ATV riding, but we wanted to introduce a whole new crowd to these amazing trails.

As far as we know this is the first event of it's kind on these trails. You won't want to miss your chance to be one of the first people to run a trail race in Black River State Forest!

You can expect a race with beautiful views, big climbs, rolling ridgelines, dense forests, and open meadows. We hope you'll find it a fun, challenging, and rewarding experience.

When: October 21, 2017
Where: Black River State Forest Smrekar Trailhead - Black River Falls, WI (Directions)
Start: 9am (25k)
Course Closes: 5:30pm (25k)

Race Day Parking

The Smrekar Lot has room for plenty of cars. If you are not able to find a spot in the lot parking is along Smrekar Rd. Please keep all four tires off the road and make sure you look for any no parking signs!

Cut-off Times

8.5 hours for the 25k. This means you'll have to average about 32 minutes per mile or better.

Race cut-offs exist for many reasons.

  1. For your safety
  2. To keep the race on schedule
  3. So our volunteers can go home at a reasonable time

No one wants to miss a cut-off and we certainly don't wish that for anyone. However, if you do miss a cut-off, please don't harass our volunteers into letting you continue. They're under orders from race staff, and that's really not fair to them.

We want everyone to be able to finish the race, but we have a couple cut-offs along the course. You'll be on-pace to finish the race in the allotted time if you make these cut-offs.

  1. Specific aid station cut-offs coming soon.

The cut-off time is the time you must leave the aid station, not the time you arrive.

Finish Line (The place to be!)

We don't have all the food and drink details worked out yet. However, there will be plenty of reasons to hang out after your race. One of the great things about the trail and ultra community is hanging out with like minded people sharing stories about your adventures. We want the finish line to be a memorable experience for all the participants. Check back here or join our mailing list for all our race day updates.
