Beautiful Sparks Marina located at 300 Howard Drive, Sparks, Nevada 89434. The marina is minutes from the Reno Tahoe Airport and is 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.
This 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, 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 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 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.
We will have a fully stocked aid station at the start/finish line providing the usual aid station fare (including Hammer Products) 24 hours per day and real meals, (Including Vegan Options) during normal breakfast, lunch and dinner hours. We are cupless so bring a cup for your cold drinks with your name or initials on it and leave it at a table at the aid station. We will provide hot cups for soup and hot drinks at night.
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. Results will be live updated on https://live.aravaiparunning.com
If you are a race director, coach, race company, running club, running gear company or running related business and you would like to partner with us to promote your event/products, please reply to [email protected]. While space lasts, we will provide room for you to set up a table at a reasonable cost.
Races with multiple start times ( 3, 6, 12 and 24 hour races) will be consolidated into a single event. For instance, the Friday 6 hour race will be combined with the Saturday 6 hour race with first, second and third place awards going to women and men in the combined event. Everyone who finishes 100 miles will receive a 100 mile belt buckle and a 100 mile finishers flannel shirt! Relay award categories include all female teams, all male teams, mixed gender ("coed") teams, 21 and under age group, and all runners over 55 years of age.
