Located at 300 Howard Drive, the marina is minutes away from the Reno Tahoe Airport and features sandy beaches, volleyball courts, a fishing pier, veterans memorial, playgrounds, coffee shops, dog parks, and scenic walking paths. The course loop runs just under two miles around this picturesque venue, allowing participants to enjoy views of the marina’s waters while running or walking.
Since its inception, the Biggest Little Ultra has attracted runners from across Nevada and beyond for a unique endurance challenge in a beautiful setting. Over the years, thousands have participated, raising funds for Liberty Dogs through their efforts, supporting the cause with every mile run or walked.
The course is paved and lighted, ensuring visibility and safety throughout its nearly two-mile loop around Sparks Marina. Participants can choose from various time options including 3-hour, 6-hour, 12-hour, 24-hour, and a full 48-hour race. Fixed distance races include the challenging 50 mile (80.5K) and 100 mile (160.9K). The relay option allows up to six runners per team for a 6-hour challenge.
Starting Friday at 9:00 am, participants have ample time with no cutoffs except on Sunday morning when the event concludes at 9:00 am. Aid stations are strategically placed along the course to support endurance athletes throughout their chosen duration or distance.
On race mornings in Sparks during October, temperatures typically range from a cool low of around 6 degrees Celsius to a high near 20 degrees with an average temperature of about 13 degrees. Humidity is moderate at roughly 47 percent and rainfall averages only half a millimeter over the course period, making for generally dry conditions despite a chance of light showers.
The Sparks Biggest Little Ultra offers runners several distance options including the full 50 mile (80.5K) race, the grueling 100 mile (160.9K), various hourly races such as the 3-hour and 24-hour events, plus a relay option for those who prefer team-based challenges.
To register, visit https://ultrasignup.com/register.aspx?did=131986 where you can find specific details on fees ranging from $75 to $445 depending on the chosen distance or time. Registration closes one week prior to each start date with no exceptions for late entries accepted.
Participants should pick up their bibs at Sparks Marina, 300 Howard Drive, starting Thursday evening through Saturday morning before race times begin. No identification is required but runners under 18 must have parental consent on file upon check-in. Age requirements vary by category; children and teens can participate in relay teams with adult supervision.
The Sparks Biggest Little Ultra at Sparks Marina provides an unparalleled experience for endurance athletes looking to push their limits over two days of racing through scenic loops around the marina, making it a worthwhile destination event for serious runners seeking both personal achievement and community engagement.
