IMPORTANT: Prior to registering for the race we require that all registrants read the race info page associated with the distance that they would like to run:

There are No Refunds, Transfers or Switches:
Entry fees are not refundable under any circumstance. Race registrations are not transferable to other participants, to future years races or to other Rocksteady Running events. We do do not allow transfers between race distances.  Please consider these factors carefully before registering.

 

Waiting List:
Once a race distance sells out, we do not keep a waiting list – instead we accept extra runners up front so that everyone has the same opportunity to train, make reservations, get a babysitter, etc. This means that a withdrawal from a sold out race prior to race day does not create an opening in the race field – it just brings us down to our predetermined field limit which is set in agreement with our permitor(s). We have found that a percentage of those who register will not make it to the starting line due to injury, illness, or other real life interventions and adjust the number of allocated spots accordingly year to year based on historical averages.

 

Cancellation Policy:
The Race Director reserves the right to modify or cancel the race or course for safety concerns, trail condition concerns, natural disaster or pandemic. In such cases there will be no refunds of race entry fees. Each athlete must accept any such risk of their entry fee paid. There is no complimentary race entry to a future race. Entry fees collected are used to develop and produce the event, starting well in advance of the race date – including course preparation, race supplies, permits, administration, staff and overhead. We will make every effort to produce a fair and safe event for all participants. Any decision we make that impacts the race date or potential cancellation is carefully considered and based on the overall event safety, sustainability and manageability.

 

Zumbro Cancellation Credit:
Rocksteady Running has successfully produced 100’s of races since 2007. Besides the cancellation of all of our events in 2020 due to the Covid-19 pandemic, the only other time we have had to cancel any races has been at Zumbro, due to (freak) snowstorms. A record setting blizzard and hazardous driving conditions forced the cancellation of Saturdays 17 mile race in 2018 while the 100 and 50 that started on Friday just barely proceeded until the end.  In 2019 another blizzard forced the cancellation of the entire event. Hunting seasons limit when we can hold Zumbro, and early to mid-April before turkey hunting begins is the most viable option available to us. In order to protect our organization and ensure that we are able to produce races for years to come, we do not offer refunds for any of our events. That said, with what seems to be a trend of severe winter-like weather occurring in early April, and the fact that there have been many “three time losers” due to cancellations (2018, 2019 & 2020 – the races were held successfully in 2021 and 2022), should we need to cancel Zumbro in 2023, we will issue a 25% credit for the 2024 race and will also mail you your swag item (t-shirt, hat, etc. / whatever it may be for the year). This will be on an opt-in basis – there will be a question during registration where you can indicate to us whether or not you would like the 25% credit to the following years race in the event of a cancellation. We are handling it this way since we know some of you will not care for it / would like to “donate” it back to us.  Please note that this policy is for the Zumbro Endurance Run only, and not for any other Rocksteady Running races. Assuming we can get through a few years without a cancellation and get back to ‘normal’, we will eventually shelf this policy as it does create added financial risk for our organization – that said, for the time being we want to be cognizant of the fact that a cancellation is not out of the question and be respectful of those of you that have stuck with us year after year.  Zumbro has been challenging, but whenever we can have it, as we did last year, it is pretty dang special and always feels like it is worth the struggle.

Registration Fee Assistance:
Registration fees are used to cover the costs of producing a race, cover overhead and hopefully provide a little bit of a cushion / startup capital for the following years race.  That said, we do not want an entry fee to be the reason that someone cannot participate in one of our races.  For each race that Rocksteady Running produces, we will make available a couple of reduced fee and / or comp entries for those in need. Please contact us via email if you need registration fee assistance and give us a brief explanation of your situation. Any assistance provided will be kept confidential. Please only request help if it is necessary, leaving the assistance for those that are truly in need.

Additionally, our Endless Summer Trail Run Series, which consists of four to five weeknight trail running races throughout the summer, with distances ranging from 5KM to 7 miles, is an ultra-low-cost event that is specifically intended to reduce financial barriers to trail racing. While the entry fee for each individual series race is only $25, we provide a full-fledged race experience including a giveaway, a chip-timed race, tons of experienced and friendly volunteers and refreshments after. These low cost racing opportunities are made possible in part by what are generally higher entry fees for our longer / ultra-distance races.  This is one way in which we can all encourage and welcome individuals from all walks of life into our awesome sport.

More About the Area:
The Zumbro Endurance Run 100MI, 50MI and 17MI trail races take place within the Zumbro River Bottoms Management Unit in Southeastern Minnesota’s Bluff Country – just outside of the tiny village of Theilman, MN approximately 1:45 from Minneapolis – St.Paul, MN.  The races start and finish at the West Assembly / Horse Campground Area.  Generally speaking the Zumbro River Bottoms Management Unit lies within a portion of the Richard J. Dorer Memorial Hardwood Forest – an expansive 1.7 million acre tract of Minnesota hardwood forest on the Northern edge of the Driftless Region which is mainly characterized by its tall bluffs and deeply carved river valleys. This “bluff country” is rugged, hauntingly beautiful and provides the perfect venue for 100, 50 or 17 miles of trail running.
