From 260 to 186: My Journey of Losing Over 100 Pounds and Becoming an Endurance Coach

Two years ago, I was stuck. After losing over 40 pounds and diving headfirst into triathlons, I felt unstoppable. I had momentum, discipline, and a deep sense of pride in how far I'd come. But then — life happened.
Somewhere along the way, I lost that rhythm. I stopped training. I got comfortable. Lazy, even. Slowly, the weight crept back on. And before I knew it, I was staring at the scale again — this time, it read 260 pounds.
It was a gut punch.
I was out of shape, winded walking up stairs, and frustrated with myself. But more than anything, I was disappointed that I had let something I’d worked so hard for slip away. And that disappointment became the fuel I needed to take action — again.
The Restart
I made the decision to lace up my shoes and go for a run. It wasn’t pretty. It wasn’t fast. But it was a start. And day by day, mile by mile, I started rebuilding.
This time, it was different.
I wasn’t chasing a number on the scale — I was chasing consistency. I committed to showing up for myself every day, even when I didn’t feel like it. I tracked my food, prioritized sleep, managed stress, and kept my running schedule non-negotiable.
Over the course of six months, that consistency paid off — big time. I dropped from 260 pounds to 186. More importantly, I reclaimed the energy, confidence, and mental clarity that had been buried under years of self-neglect.
Becoming a Coach
With this transformation came something unexpected: people started asking for help. They saw my progress and wanted to know how they could make a change too. That’s when I realized — my journey could be someone else’s roadmap.
So I got certified and became an endurance coach.
Now, I have the honor of helping others transform their lives the way I transformed mine — not just through training plans and pacing strategies, but through building belief, discipline, and grit.
Lessons Learned
You’re never too far gone. Whether you've gained weight back or feel like you're starting from scratch, progress is always possible if you're willing to put in the work.
Consistency beats perfection. I didn’t get from 260 to 186 by being perfect. I got there by not giving up.
Movement is medicine. Running gave me my life back — mentally, emotionally, and physically.
Helping others multiplies the reward. Becoming a coach has been one of the most fulfilling parts of this journey. Watching others succeed is even better than hitting your own PRs.
This journey has been anything but linear. There were setbacks, doubts, and plenty of hard days. But through it all, I kept going — and that’s what made the difference.
If you're on a similar path, know this: it’s never too late to start again. The version of you you want to become is waiting — you just have to take the first step.
