The 12.5K loop course is primarily an equestrian trail consisting of mowed grass and dirt. Depending on conditions, it is very suitable for a first-time ultra-trail run. Spring in Minnesota can bring just about anything: sun, rain, mud, snow, ice — we’ve seen it all! Please prepare accordingly. For runner safety, the course may be altered due to trail conditions.
The 50K race is four laps, the 25K is two laps, the 12.5K is one lap. The 6K course will be two laps and is partially run on its own course. Lap split times will be available. All 50K runners must begin their final lap by 2:00 PM. Runners behind this schedule will be pulled from the course and not allowed to continue. Timing and post-race food will be available for all runners who start their final lap by 2:00 PM regardless of finishing time.

Frequently Asked Questions
What is the course like?
The course follows the equestrian trails of Lake Rebecca Park Reserve and offers a variety of scenery. The trail surface is packed dirt and grass. There are several moderately difficult hills within the route, with limited roots and rocks. Lower areas and those in dense woods may have mud or standing water of a few inches. Like any trail, runners should take extra care with their foot placement during the race. See the course map link for route details and an elevation chart. You can also view last year’s results to get an idea of how long it took most people to complete the race.
What is the refund policy?
The race will take place rain, shine or snow, and entry fees are non-refundable. Race start times may be delayed if severe weather is imminent.
Can I change my registration to a different race length?
Yes, runners are allowed to change races. However, after April 4, a $20 race change fee will apply, and you will pay the difference in registration fee, using the fee structure corresponding to the date of registration change. If you move to a race with a lower registration fee, you will not be refunded the difference.
What if there is bad weather?
The race will go on! Spring weather in Minnesota is highly variable and past Trail Mix participants have run in the sunshine, in the cold, through rain, in a few inches of snow and through plenty of mud. Lightning may delay the start of the race. If the weather is deemed too dangerous, the race will be cancelled. Refunds will not be issued for event cancellation.
Can I pick up someone else's race packet or can someone else pick up my race packet?
Yes, packets may be picked up by someone other than yourself. The person picking up your packet assumes all responsibility for lost race bibs and/or t-shirts.
Are there restrooms on the race course?
Yes, there is one at each of the aid stations and near the start/finish area.
Can I wear headphones during the race?
Yes, although we ask that you keep the volume at a level that will allow you to hear other runners, race officials, etc. Please be aware of your surroundings.
