Beautiful Sparks Marina located at 300 Howard Drive, Sparks, Nevada 89434. The Sparks Marina is minutes from the Reno Tahoe Airport and adjacent to several hotels and casinos. Once a quarry, Sparks Marina now is a popular spot for fishing, swimming, sailing, windsurfing and scuba diving. It has a large dog park, sandy beaches, volleyball courts, a fishing pier, veterans memorial, kids playground, coffee shop and, most importantly, a comfortable and scenic walking path around the marina. The marina is the centerpiece of the Biggest Little Ultra and provides a pleasant backdrop for your race.

The Sparks Biggest Little Ultra is a fixed time/fixed distance race held over two days for runners and walkers. We offer fixed time options of a 3-hour, 6-hour, 12-hour, 24-hour, and 48-hour race, as well as fixed distance options of a 100 mile and 50 mile race. All these Biggest Little Ultra races start Friday, October 9, at 9:00 am.

Saturday Options for Fixed Time Races: For those who cannot arrive on Friday, we also offer a 3-hour, 6-hour, 12-hour, and 24-hour race starting Saturday, October 10, at 9:00 am. The 48 hour, 100 mile and 50 mile races end Sunday, October 11, at 9:00 a.m. YES no cutoff (except 9:00 a.m. Sunday) so plenty of time to achieve your goal!

Relay Option! The 6-hour relay starts on Saturday, October 10, at 9:00 am and ends 6 hours later at 3:00 pm. You may have up to six relay runners on your team. Award categories for all female teams, all male teams, mixed gender ("coed") teams, all runners 21 and under, and all runners over 55 years of age. So, here is a chance to gather folks from your organization, neighborhood, or family to share miles, laughter, and achievement! We want as many people as possible to get moving and exercising. All ability levels are welcome, so don't worry if your team members are not all speedsters. Show up as a team, create a name, and go for it!

The Sparks Biggest Little Ultra is your chance to set a P.R. at your chosen distance. It is paved and lighted so the course loop is safe and visible. Tired of stressing about aid station cutoffs? This race is the solution. Maybe you just want to cruise with friends and enjoy a glorious venue. Or, let's find out how far you can go in 3, 6, 12, 24 or 48 hours. In addition, we provide great swag and we will make a contribution to a very worthy cause (Liberty Dogs).

"The real purpose of running isn't to win a race. It is to test the limits of the human heart."
Bill Bowerman

About The Race

The race course is just under a 2 mile loop around beautiful Sparks Marina. Total elevation gain is 29 feet. The course is paved and lighted so no gators or headlamps are required. Two real restrooms are along the course and porta potties will be near the start line. We will not count partial laps. So, know your split time toward the end of your race and do not go out if you see you cannot finish the lap before your race ends. 50 mile runners will run 26 loops and the 100 mile runners will do 52 loops.

Please note your watch may show a different distance but we are using our official course measurement calculation for race results.

One pacer at a time is allowed during the entire event. No bikes, please.

Your time and distance for each completed lap will be recorded automatically using an electronic chip based timing system. You will be issued a timing transponder/chip. It is the runner's responsibility to have the chip on their person at all times! Laps done without a chip are not counted by the timing system. There are no exceptions! A secondary timing system will be placed halfway around the track to verify laps completed. Up-to-date lap totals will be displayed instantaneously when runners cross the start line.
