About This Page:

The information on this page and associated links comprise the official ESTRS Spring Lake 5 Mile Participant Guide. It contains all of the information and links you will need in order to research, register for and run the race. Runners are required to review this page, along with the registration info page in their entirety prior to registering for the race. This information should then be referenced as needed in the months and weeks leading up to the race. Keep in mind that information may be updated and changed right up until the race, so a final review of the information about a week out is encouraged. Registered runners can expect a welcome email from us with any new / additional information the day before or morning of the race. This page contains the following sections:










About the ESTRS Spring Lake 5MI:
The Spring Lake 5 Mile consists of a fun and very runnable but rolling 5 mile course consisting of two loops in a figure-eight configuration. There is a mix of wide mowed trails through the prairie and single and double-track trails in the woods.  There will be a water stop (and some mad cheering) after your first loop / approximately 5KM into the race. The elevation gain for the race is about 310 FT (62 FT per mile).


About the Endless Summer Trail Run Series:
Remember when you were young and the summer days were hot, relaxing and seemingly endless?  Well, as adults we still get that, but usually only on weekends and holidays… until now.  The Endless Summer Trail Run Series is brought to you by two passionate Minnesota trail-running main-stays – Rocksteady Running and Twin Cities Running Company.  The series was created to provide low-cost and low-pressure trail running / racing opportunities for people of all ages, abilities and levels of experience. Whether you are a seasoned trail or road racer, first time trail-racer, need a tune-up for your next goal race, need to get in some speed-work or just want to enjoy some social time and refreshments with us at the finish – running one or all of the races in the series is for you.  The Endless Summer Trail Run Series has garnered a strong local following and has gotten significant national media coverage as one of the best organized and most well attended trail running series in the country!

About Rocksteady Running:
The Endless Summer Trail Run Series is organized by Rocksteady Running and directed by John Storkamp. Rocksteady Running produces several trail and ultrarunning races in the state of Minnesota. Our races are put on by longtime trail and ultrarunners. Our focus is on sustainability, runner safety, runner experience and giving back to the trail, parks and communities where our events are held. Our mission is to create experiences that facilitate connection.​ All credit is due to our army of volunteers and our wonderful Minnesota trail running community.


All Are Welcome:
Rocksteady Running welcomes everyone to our events and into our broader trail running community. You are welcome and valued regardless of your race, gender, sexual identity, orientation, or preference, religious, spiritual, or political beliefs, socioeconomic status, age, how quickly or slowly you run. Please be kind, and treat others as you would like to be treated.






Do not register until you have reviewed this page (ESTRS Spring Lake 5MI Participant Guide) in its entirety. Once registration is open, complete details including entry fees, field limits, and the link to our registration page on UltraSignup (our third party registration provider) can be found HERE https://www.estrs.com/registration-info/


Field Limit:
450 Runners


Entry Fee:
$30 (+UltraSignup Fee)


There are No Refunds, Transfers or Switches:
Entry fees are not refundable under any circumstance. Entry fees will not be refunded if a runner chooses not to, or is unable to race, for any reason. Entry fees will not be refunded if the race is canceled, for any reason. Race registrations are not transferable to other participants, to future years races or to other Rocksteady Running events. Transfers are not allowed between race distances.  Runners should consider these factors very carefully before registering. Runners who are not comfortable with these policies should not register.


No Waiting List Will be Kept:
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, natural disaster, public health emergency, air quality, public safety threat, severe weather, trail condition concerns, etc. 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 and administration. 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.


Registration Fee Assistance:
The Endless Summer Trail Run Series is an 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 $30, we provide a full-fledged race experience including a giveaway, a chip-timed race, tons of experienced and friendly volunteers and refreshments after.

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 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.






What’s Included With Your Registration:
A well marked course, a water stop at races 5KM and longer, chip timing and tons of friendly, experienced volunteers. Each nights giveaway will be a sticker. Hang out after for Domino’s Pizza, soft drinks and beer and most importantly, fellowship!


How We Will Communicate With You Once You Register:
Immediately after registering you will receive a registration confirmation email from our registration provider UltraSignup. Your name will also be added to the list of registered runners which can be found on our website under the menu item(s) RACE > REGISTER > WHO’S REGISTERED. You will receive a welcome email from us with any last minute updates either the day before or day of the race. About a week after the race we will send out a thank you email / race recap. We will email you at the address that you have one file with our registration provider UltraSignup. Please make sure that your email is up to date with UltraSignup / was inputted correctly – if it is not, you will not receive our communications. You may also want to add [email protected], [email protected] and [email protected] to your email providers ‘do not block’ / ‘do not spam’ / ‘white list’ / ‘safe’ list. A copy of every race email sent will be immediately added to our website HERE https://www.estrs.com/news-and-updates/ Most importantly, everything you need to know can be found on the Zumbro Endurance Run website. If at any point you have questions, please contact us. You can also ask questions of your fellow runners in our online community / forum HERE https://community.rocksteadyrunning.com/


If You Have Registered and Can No Longer Run:
If you are registered to run and can no longer make it, you DO NOT need to notify us. Once a runner is registered, we do not remove them from the roster until race day, if / when they don’t show up. We handle it in this way because it is not uncommon for a runner to notify us that they will not be running, then notify us that they will be, then notify us again they won’t be, and so forth – this sort of thing creates confusion and leads to check-in and timing mistakes when we start modifying the runner database. We will know if a registrant is not running when they do not check in / pick up their race number on race day. You WILL NOT be publicly listed, or “reported” as a DNS / Did Not Start.


Race Date, Time and Location:

Wednesday July 31, 2024

Race starts at: 6:30 PM

Spring Lake Park Reserve
8395 127th St E
Hastings, MN 55033 

Driving Directions HERE


There is more than enough parking onsite and on the road leading into the park.  Those arriving late, be prepared for a 5 to 10 minute walk. Parking volunteers will direct you as soon as you enter the park.  A detailed map showing available parking can be found HERE


Check-In / Race-Number Pickup & Race Start :
You can pickup your race number starting at 5:00 PM on race day. The race will start promptly at 6:30 PM.  If you are over 21 and would like to have a beer after, please bring your ID to check-in and you will be given a wrist-band.  Due to rush hour, we strongly encourage you to leave work (or wherever you are coming from) early so as not to arrive late to the race – those who arrive after the start of the race will not be issued a number or timed but are welcome to go out and run on their own (and not cross the finish line) and join us after for refreshments!


Weather, Heat & Thunderstorms:
It’s Summer, it can be hot.  For races over 5KM we will have a water stop around the half way point. For races 5KM and shorter there will be no water stop. Be sure to carry water if you feel you will need it. We expect that you will use your personal judgement in deciding if it is too hot for you to run.  The race will be held rain or shine – however, severe weather is a different story.  To date we have never called off a race early / in advance due to the potential for severe weather – hopefully, the worse case scenario would be a delay in the start time once unsafe weather conditions have passed.  If sever weather were to persist after a reasonable amount of time we would call off the event.


Race Numbers & Timing Chips:
You must wear your race number and it must be clearly visible on the front of your body at all times.  Your timing chip will be affixed to the back of your race number.  Do not remove your timing chip.  Do not bend or fold your timing chip or crumple your race number – this may break your timing chip. Your race number and your timing chip must be pinned on your outer-most layer at all times.  Above guidelines must be followed in order ensure that your finish time is recorded. This chip is disposable and does not need to be returned. More info HERE


Course Markings:
The course will be marked with orange survey style pin flags, which will always be on the left hand side of the trail except in areas with two way traffic, in which case flags will be on both sides of the trail. Since our races take place at parks that are open to the public we DO NOT block off trails that you are not supposed to go down, instead we mark the route that you are supposed to take. It is unfortunate but is not unheard of at trail races that course vandalism has occurred and flagging has been intentionally moved or removed by small minded individuals – it is important that you study the course maps prior to running and try to have some concept of where you are going.


Race Course:
A map of the race course can be found HERE


Water Stops:
For races over 5KM there will be a water stop approximately 1/2 way through the course. There will not be a water stop for 5KM (3.1 mile) or shorter races.  If you feel you will need water during 5KM or shorter races OR feel that one water stop for races over 5KM is not enough, please plan to carry a water bottle.


( Aspiring ) Cupless Race:
The Endless Summer Trail Run Series races are NOT cupless. Another way of saying this is that for ESTRS races with water stops, we WILL provide cups to drink water out of.  All of the other non-ESTRS Rocksteady Running races are however, cupless. What this means is that at those races, if you want to drink water at the water stops, you have to have your own cup (or water bottle). If you would like to go green and / or practice for other / longer RSR races you can procure you own cup ahead of the race. If you are not familiar with these reusable cups they are easy to find and procure, HERE https://hydrapak.com/products/speed-cup-200-ml is one example.


Headphones are allowed. Please keep the volume low, or one earbud out so you can hear what is going on around you. Full awareness of one’s surroundings, and the ability to communicate with other participants, race volunteers, and trail users not associated with the event are critical to everyone’s safety.


Out-Loud Music:
Playing music out-loud from your phone or other speakers is not allowed.


You may not run the race with your dog. Supervised on-leash dogs are welcome at the race with your family / spectators.


Please help to keep the trail clean.  Try not to drop anything, and if you see something that someone else has accidently dropped, please pick it up.


Current year results will be available on our website under the heading Race > Results. As long as we can maintain internet connectivity, results will be published in real time as runners finish. Past results can be found HERE https://www.estrs.com/results/ Course records can be found HERE https://www.estrs.com/records/


There are no specific overall winner or age group awards. You are all incredible.


Post-Race Festivities:
We will be serving Domino’s Pizza, soft drinks and Beer after the race. Please stick around after, this is what this race is all about, enjoying Summer to its fullest, meeting new people and enjoying our awesome local trail-running COMMUNITY!  * Please note that if you would like to have a beer after the race, you will need to show ID just as you would have to at a bar / restaurant, once you show your ID you will get a wrist-band… we prefer you have your ID when you pick up your race number but you can show it later as well.


For those interested in volunteering, more information can be found HERE https://www.estrs.com/read-first/
