Jeff Lingle

Jeff grew up in Long Beach, CA and spent most of his childhood shooting hoops, surfing and doing tricks on his BMX bike. Although an active kid, Jeff fell into some sedentary habits for a few decades as an adult working in IT.  In 2009, he found himself in a spot where his personal life and health were a wreck and he signed up for the Long Beach Marathon as a way to cope with stress and try to become healthier.  He discovered a passion for running while training for the Long Beach marathon.  With some encouragement from his wife, Jenny, and a college buddy, he signed up for his first triathlon in 2014 and completed the Olympic distance Morro Bay Rock the Tri race using a rented wetsuit and a borrowed bike and battling a crazy riptide on the swim!  Even still, he was hooked! Since then, he has developed a passion for integrating exercise and nutrition into his daily routine. He is an avid swimmer and bike commuter to work. He loves doing open-water swims, triathlons of all distances, and getting friends together to go for a “big ride”!! Marathon swimming and triathlon training has been transformative and has brought him some of his closest friends. In addition to triathlons, Jeff is passionate about making the world a better place through exercise, eating tacos with friends, and enjoying a great cup of coffee.

Mila Griffin

I grew up in Europe and competed in Track and Field from a very young age all the way through high school. I continue running through my adult life but did not discover triathlon until 4 yrs. ago when my best friend did her first Ironman. I was so moved by the experience that decided to give it a try. I was always very active and outdoorsy, I knew how to bike and swim (or so I thought) so I hired a coach and did my very first Sprint triathlon Tribella at Cherry Creek in 2017. It was a love from first sight, and I was hooked. Since, I completed my first Ironman Boulder in 2019 and have done numerous 70.3 and shorter distance triathlons. Other than triathlons, I am a busy working mom of two young ladies, who are even more competitive than me and am I am married to Tony who completed the Ironman Boulder with me last year just so I have a training partner. We love skiing and traveling as a family and can’t wait for our next adventure..

Coaching Director

Leslie Beahm

Leslie is a military spouse (retired) who moved to Colorado in 2014, a mother of two almost-grown boys, and an electrical engineer who does power distribution, systems, and lighting design for buildings. 

Leslie has been competing in triathlon since 2017, when she found a flier for a beginner triathlon group at her local Rec Center. AT that time, she couldn't run two times around the indoor track without needing to stop for a breath (2/11 of a mile!). She has now completed a handful of half-Ironman races and a full Ironman. She is excited, as a USAT Level 1 coach to bring her passion to Altitude Multisport Club as a Coaching Coordinator.

Sponsorship Director

Bryan Upcraft

Bryan started his triathlon journey leading up to his 50th birthday in 2019. He was able to tread water and get back to a boat, but not “swim” any distance. After deciding to do a Full Ironman for the occasion, he met a group of folks from AMC. His first year of races consisted of two Olympic distance, one Half Ironman and a Full Ironman. It was an exciting realization of what a body can do.

After meeting the group at AMC, the good times began. Bryan is grateful for all the wonderful people in AMC who have coached, helped and taught him what it takes to set accomplish lofty goals. He is excited to help the club and community that have done so much for him.

Beth Nixon

Beth grew up in Michigan, the youngest of 5 kids. She was always active in school sports, playing volleyball, softball and basketball. Her brothers were both competitive swimmers, but horses were more her “thing”. Also, she hated running - so the thought of triathlon never even crossed her mind. Beth moved to Colorado after finishing graduate school. Her life changed in August 2014 when she was diagnosed with breast cancer. She had started working with a trainer a few months before, and continued to work with him throughout months of chemo and radiation treatments. Some days sucked, no lie, but training was the only thing that made her feel close to “normal”. As Beth neared the end of her treatments, her trainer encouraged her to try out a bike race. Never mind that she didn’t own a bike at the time…it sounded like a fun challenge. One race and she was hooked. When he suggested she try a triathlon, Beth thought he was crazy, but what the heck? She did her first sprint triathlon in August 2015 – one year after her diagnosis – take THAT, cancer!

Since then it’s become one of Beth’s passions – she participates in numerous sprint and Olympic distance triathlons each summer (and aquabikes, because she still hates running!), and in 2019 she finished her first Ironman 70.3 in her home state of Michigan. Beth started triathlon for the challenge. She’s stayed with it because the triathlete community is made up of amazing and supportive people. What Beth finds most rewarding is having an opportunity to bring new people into the world of triathlon – people who didn’t think they could ever do “something like that”. Beth was one of those people herself, and she knows that if you set your mind to it, “Anything is Possible”.

Tony Griffin

Tony is a pseudo-triathlete, who doesn’t enjoy the water as much he used to.  He satisfies his competitive streak by living vicariously through his wife and kids’ activities, and the occasional duathlon, road race, and triathlon.
