A one-day 9-hole stage race where the lowest cumulative score wins
June 28th, 2025
Creekside Trails, Valparaiso, IN
Event Overview
Don’t let the name fool you, there’s no clubs or balls involved. This is a trail running endurance challenge like no other! The object of the game? Complete the routes with the lowest cumulative score and you win. Simple enough. But wait, “score”? Don’t you mean “time"? Not quite…
Here’s how it works: At the top of each hour everyone will start the same route, or “Hole”, of about 3-4 miles in length. Depending on the time window you finish in, you’ll receive a stroke score (“Birdie”, “Par”, “Bogey”, etc). 9 Holes in total for the 50k, 3 Holes for the 10-miler. Like in golf, the goal is to have the lowest score.
The time windows have been calculated for each Hole and are based on the total distance covered and overall pace (see table below). For example, if you run 10-12min/mile pace for each hole, you’ll be hitting Par. For scoring, “Eagle” is always 2 strokes, “Birdie” gets you 3, “Par” is 4, and so on.
50K & 10M starts with Hole 1 at 9:00 AM
On average, each hole has about 190ft of gain with a total of 1700ft for the 50k and about 500ft for the 10M
The time between finishing a hole and the start of the next is your time to rest, refuel, and receive aid from your support crew, or “Caddies”, before the next “Tee Off”
Rules:
Everyone starts each Hole at the designated Tee Time (see table above). No one may tee off early.
You may tee off late (up to 10 min), but everyone’s official start time will be at the top of the hour (Tee Time), regardless of when they actually start
If you skip a Hole (DNS) or do not completely finish it (DNF), you will be given an automatic Triple Bogey, a stroke score of 7
In the event of a tie in score, the tiebreaker will go to the runner or team with the lowest cummulative time on course
Runners are responsible for their own aid, but we will have water, Tailwind, and coffee available for RUNNERS ONLY
Runners will be able to setup a small tent/canopy (no larger than 10’x10’) for themselves and their caddies (support crew) within 50 yards of the start/finish
Once you are on course, you are not allowed any aid from your caddies or otherwise
There will be no aid or water stops on course. Carry any hydration or fuel you may need with you
Runners must remain on the designated course for each Hole. If you veer off course, you must return to the spot at which you left the course to continue, or risk a 2 stroke penalty, at minimum.
If you choose not to continue, you must inform the race crew and turn in your tracking device before leaving the premises
For Relay Runners:
Relay teams may be made of 2 or 3 runners
Only 1 runner from a team may be on course at a time
You are not required to rotate through your team in any consistent order, nor are you required to evenly divide up the Holes. Each teammate may run as many or a few Holes as they prefer.

Aid Stations
There will be no aid or water stops provided on course. Runners are responsible for their own aid. Bring a cooler or bag with whatever fuel you need throughout the day. Carry any hydration or fuel you may need on course with you. We will have water, ice, Tailwind (electrolyte drink), and coffee, bananas, watermelon, and other salty/sweet snacks available near the start/finish.

Cupless Event
We feel so fortunate to make the outdoors our passion and we want to continue to keep the trails we enjoy beautiful and free from trash. In an effort to minimize our footprint and preserve the trails we love, the 2025 Trail Golf Endurance Challenge will be a cupless event.
What does that mean? There will be no paper/plastic cups available for water, soda, electrolyte drink, etc. at this race (the restaurant will have their own glassware). Runners will be responsible for carrying their own containers to refill. Grab a cup, a hydration vest, pouch, or reusable water bottle and fill it up near the start/finish. We ask you to help us in our efforts by preparing for a cup-free race day and thank you in advance for being good stewards of the trails!
Parking
We’re currently working on a plan for parking. It may involving shuttling from a nearby lot, as we won’t be able to utilize Trailyard’s lot this year. In any case, parking will have no fee. Please plan to carpool if possible, as parking may limited. A site map will be provided in pre-race email communications to all registered participants.

FAQ
-
You’ll receive a Double Bogey (6 strokes).
If you complete it within 10min past the hour and are ready to start the next hole, you’ll be allowed to continue (you’ll just have less time to complete the next hole so you’ll want to pick up the pace).
If you come in after 10min past the hour, or do not start the next hole by then, you’ll receive an automatic Triple Bogey (7 strokes) and will have to wait till the start of the following hole to continue, if you choose to.
-
No. Everyone starts the same hole together at the same time
-
Yes. We’ll have some light snacks and fruit (think basic ultra aid station fare) available near the water station for throughout the day for all runners. We’ll start serving grilled burgers and such around noon. The Trailyard restaurant may or may not be fully open by race day, so that may be an option for you as well (food from Trailyard is not included in the race fee)
Runners and their caddies (support crew) may bring in whatever food and drinks they may need throughout the day. You can bring a cooler/bag and place it under your tent or resting area for this purpose.
