T.R. Jamar
All Mountain Coach
Endurance sports are a continual learning ground, but the strongest impression they have made on my life so far is the understanding that we can truly accomplish anything that we set our mind to, make a plan for, and stay consistent with. I coach to help other people reap these benefits that carry over into all aspects of life as well. I’ve been running ultras and pushing the limits of endurance for a while now, but the “ah-ha” moment for me was walking through the airport with the aid of trekking poles and gnarly blistered feet after completing my first 200 mile race (Moab 240 in 2022). That is when I realized the essence and truth of the sentence above: that we all have the capacity to push well beyond our current known limits. I am an All Mountain coach with Boundless to assist athletes chase and surpass goals by training body and mind to go where they have never gone before.
My fitness training background started in the Navy as a physical readiness coordinator for my command. Upon separating from the military I began coaching CrossFit, and found great enjoyment in witnessing bodies and mindsets shift through physical challenges. My passion for movement eventually led me to running and biking as a way to get out of the classroom and explore outside more when I was in physical therapy school. Half marathons turned into trail ultras and eventually multiple 200+ mile running event finishes. In recent years, especially since we have started a family (wife and 2 kiddos under 3 years old) biking has become more of a passion of mine culminating recently with a Leadville 100 MTB finish in 2026 as part of the Lead Challenge.
I understand that everyone who signs up for these events has busy schedules that don’t always go according to plan. Even when training doesn’t go perfectly, the dedication, commitment, and sacrifice to a task is all part of the process that I believe makes us better athletes and humans. Race day is hopefully the celebration of a good training block. The physiologic adaptations we develop along the way help us function better, stronger, and faster in all aspects of life. My hope for all of my athletes goes beyond a successful finish time. I hope those good training blocks stack on top of each other and alter the trajectory of a life for the better. I know that Boundless shares these values also, and that is why I am proud to coach for them.
These days I mostly train with the thought of being an example of health, fitness, and moving well through nature in the hopes that my children are inspired to do the same. My pie in the sky dream is that maybe one day a long time from now my family will all run/ride an ultra through the mountains together! What is your big scary goal? I’m stoked to help you get after it!
