About 4 Fore 30 Infinity

We're back for the fifth year and it's going to be bigger and better than ever!

4 Fore 30 will follow all the rules of Big's Backyard Ultra.

At 7:00am on Saturday, December 2, 2023 everyone will line up at the start and have 1 hour to complete the 4.1667 mile loop around the golf course. Go as fast or as slow as you want, just be done in an hour, because... at 8:00am everyone lines up to do the next loop. At the top of each hour, the process repeats until there is only one person remaining.

All runners will receive race swag and a meal coupon for use at the golf course restaurant.

100% of profits go to the Kids' Harbor Child Advocacy Center.

Course description

The course will use the cart paths of Lake Valley Golf and Country Club. You are not required to stay on the paths. You can run in the grass next to the paths if you prefer. There is an average of approximately 100 feet of elevation gain per mile.

Aid Station

There will be a single aid station at the start-finish line. Runner will also pass the aid station just past the 2 mile mark.

Runners will have access to the restrooms on the golf course, if they are still open for the season.

Runners, crew and spectators can also use the restroom and restaurant inside the golf course pro shop. There will also be porta-potties.


Several hotels and motels are available a short drive from the course including Old Kinderhook Lodge and the Sleep Inn in Camdenton.


Runners will receive a coupon for a hot meal at the golf course restaurant for use during business hours. Crew and spectators will also have access to the restaurant for the duration of the event.

In addition we will serve a free breakfast for all runners on Sunday morning (even if you are no longer running).


The start-finish area will be lit (figuratively and literally) but you will want to to carry a headlamp or flashlight with you during the night hours. Due to inconsistencies in the cart paths and other potential obstacles, it will be a good idea to see where you are going. When the race starts at 7:00am, lighting will not be needed but if you plan on going more than 10 hours, it will be necessary.


Sorry, there are no refunds. 100% of race profits go to Kid's Harbor. However, you can transfer your bib to another runner up to one week from the race.
