OLATHE, Kan./July 22, 2025 - Garmin (NYSE: GRMN) today announced the full marathon, half marathon, 10K and 5K courses for the Garmin Marathon Series in Tucson, Arizona. Designed in cooperation with Run Tucson, the routes feature the beauty of the Sonoran Desert, surrounding mountain ranges and rich cultural heritage of "The Old Pueblo" metropolitan area, known for its thriving food and art scenes.

"The Tucson Garmin Marathon Series will be a standout race experience for all participants and spectators. We know a memorable race deserves an equally memorable prize, and that's why we're awarding first-place finishers and age group winners in the full marathon with our feature-packed Forerunner 970 premium running smartwatch, and all half, 10K and 5K first-place and age group winners will receive the popular Forerunner 165."
- Susan Lyman, Garmin Vice President of Consumer Sales and Marketing

All course distances start and finish in the heart of downtown Tucson, near the State of Arizona Governmental Offices on West Congress Street, west of North Granada Avenue. Full marathoners, half marathoners and 10K runners begin at 7 a.m. and run the first two miles together, initially heading west past the Mercado District and the Desert Laboratory on Tumamoc Hill, an 860-acre ecological preserve. The 5K participants follow at 7:20 a.m.

Full Marathon
After continuing past Pima County Community College, runners keep going west as they run along the southern perimeter of Painted Hills Trails Park, a 285-acre natural open space park known for its saguaros. Returning east on West Speedway Boulevard, participants will see Greasewood Park, El Rio Golf Course and stunning views of the Santa Catalina Mountains to the north before reaching the University of Arizona campus. They then continue on East 3^rdStreet, turn south at North Alvernon Way and loop around Randolph Golf Campus before heading east on Broadway Boulevard down the Sunshine Mile toward downtown Tucson. The final section has them crossing South Freeway on West 22^nd Street, turning right and running north on South Grande Avenue, before finishing by going east on West Congress Street back into the city center, the heart of this vibrant desert community.

The full marathon course, which is pending USATF and Boston Marathon qualifier certification and subject to change, features a total ascent of 948 feet with the majority of it occurring in the first 5 miles and a cut-off time of 6.5 hours.

Half Marathon
Those participating in the half marathon run with the full marathoners until they reach the northern side of Painted Hills Trails Park. They then split away from the other runners for two miles, before rejoining them on West Speedway Boulevard. At the Santa Cruz River, half marathon participants head south on the Tucson Loop - a scenic 138-mile paved path encircling the city - for a little over a mile before connecting with the main route on West Congress Street and finishing at the start and finish line. Total ascent for the half marathon, also pending certification, is 738 feet and the cut-off time is the same as for the full marathon.

10K and 5K
