Anthony Trimble - Owner 

I've been an athlete my whole life and played soccer, basketball, track & field, and tennis in school. After high school, and graduating from Sinclair Community College and the University of Dayton, I started distance running with 5Ks, 10Ks, half marathons, and full marathons. My first marathon was the Cincinnati Flying Pig Marathon in 2001. After marathon running I starting competing in triathlons. I've completed multiple sprint, olympic, half ironman distance triathlons and one full ironman distance triathlon. I'm also a former USA Triathlon Level 1 Certified Coach and Trustee/Race Director for the Ohio River Road Runner Club. I'm a Nationally Recognized Gold Circle Jaguar Certified Timer and Advisory Board Member for Innovative Timing Systems.


Giving back to the community and volunteering my time is important. I am proud to be a founding member of the Dayton Chapter of Team Red, White, and Blue (Team RWB).  

As a participant, my favorite running event has been the Key West Half Marathon. How can you go wrong with sun, sand, and the ocean breeze for 13.1 miles!

Aneesa Bhimani-Trimble - Owner 

I was introduced to the Dayton running community in 2001, when I ran the Turkey Trot in Miamisburg. I enjoy the energy and excitement of running events and getting to know participants, so you'll often find me at the finish line cheering people on and talking when I should be working. I'm a former Trustee/Race Director for the Ohio River Road Runner Club. I'm also a Nationally Recognized Gold Circle Jaguar Certified Timer and Advisory Board Member for Innovative Timing Systems.

When I'm not working events or chasing after our son, I enjoy volunteering my time with several community organizations. I'm also proud to be a founding member of the Dayton Chapter of Team RWB and a member of the Dayton She Runs This Town (SRTT). 

Locally, I've participated in numerous community 5Ks and completed the Outdoor X 12 Hour Endurance Run. My favorite running event is also the Key West Half Marathon. There's something special about running along the ocean as the sun is rising.

Nick Landis - Team Member


Nick has worked for Key Sports since 2016 and loves all things associated with racing. He can be found on race day setting up tents and finish lines or even leading the race on his bike. Nick himself has competed in running races as well as several triathlons. His true passion is cycling and more often than not can be found on two wheels. Nick's favorite race was the Camp Arifjan Sprint Triathlon, where he had the fastest time in his Unit and recalls how horrible it was to ride a cheap mountain bike through the desert for 20K. Nick's most accomplished event was earning a Silver German Armed Forces Proficiency Badge, with only 24 hours notice.
