“This is the second year of United’s title sponsorship, and we’ve enjoyed a close working relationship with them and Guam Visitors Bureau (GVB) this past year to promote UGM overseas. We had good international participation. Half of our participants traveled to Guam to enjoy the event and vacation on island,” said Ben Ferguson, managing director of Guam Sports events, Inc., organizers of UGM.

“It’s humbling to see our community come together with such energy and great Hafa Adai spirit to support this international event that all of our residents can be proud of,” he added. “We’d like to recognize and thank all our sponsors, community partners, participants and volunteers who made UGM 2018 a great event. We hope to see everyone at the seventh annual United Airlines Guam Marathon on April 14, 2019!”

Sam Shinohara, United’s managing director of operations Asia/Pacific, said, “United is very proud of our UGM title sponsorship. This event means so much to our company and almost 1,000 employees that call Guam home, because it allows us to proudly carry out our role as Guam’s hometown airline. We are excited to have kicked off United Airlines’ 50th anniversary celebration at UGM, giving away roundtrip tickets at the start of each race. We thank Guam Sports Events for putting on such a great event. We look forward to getting back to work to promote UGM 2019.”

Nate Denight, president and CEO of Guam Visitors Bureau, said, “We’ve been working since last year to promote UGM in our source markets. Sports events such as UGM are great for the island, because it allows the community to come together with our visitors to share our Hafa Adai spirit. Thousands of international visitors are now enjoying our beautiful island after the race and contributing millions of dollars to our local economy. We thank Gov. Calvo, Lt. Gov. Tenorio, the Guam Legislature, and the many government agencies and tourism industry partners that have supported this GVB signature event.”

UGM welcomed Naoko Takahashi, a 2000 Sydney Olympics gold medalist, returned as the 2018 international race ambassador. Ms. Takahashi held running workshops at the two-day Håfa Adai Expo and cheered runners throughout out the course.

Sponsors and race volunteers took on a total of 15 aid stations, offering runners local snacks such as apigigi and coconut candy. After the race, runners and their families enjoyed the BBQ Beach Party that featured live local entertainment and food and beverages at Ypao Beach  overlooking the beautiful Tumon Bay and Two Lovers Point.

Complete race results will be posted on unitedguammarathon.com and on the UGM app.
