Sometimes the hardest thing I ask of an ambitious athlete to do is less.

Katie came to me with no shortage of work ethic.

She’d done bodybuilding. Long-distance running. HYROX. Ironman training. She knew how to push herself, and she was more than willing to do it.

What she didn’t need was another coach giving her more things to accomplish.

She needed someone willing to look at the whole picture and ask:

What does your body actually have the capacity to adapt to right now?

Over the last year, we’ve built more structure around her training while intentionally removing some of the extra activity she thought she needed. Considering what her Garmin metrics are saying about her habits, noting health symptoms that have become patterns, and learning to trust that while less isn’t more, it’s actually better… in so many ways.

Just yesterday, she sent me a reflection that had me teary-eyed.

“Following your plan and DOING LESS than what I used to has made my body respond in the most positive and loving way.”

That’s the work.

Not seeing how much training we can cram into a week.

Not handing an ambitious person an ambitious-looking plan.

Not confusing exhaustion with effectiveness.

It’s figuring out the right dose of running, strength, intensity, recovery, nutrition and life stress for the actual human being in front of me, and adjusting it as that person changes.

Katie still has big goals. She talks about becoming competitive in ultras down the road.

But after nearly a year together, one of the biggest things she’s gained aside from her fitness is confidence in her body.

A confidence that she doesn’t have to constantly prove how badly she wants something by doing more.

You can be deeply ambitious without constantly asking more of yourself.

Sometimes the path to finding out how good you can get starts with finally giving your body enough room to recover.

I’m really happy for Katie and honored to be a part of her journey.

“I want to like myself at the end.”

Rachel Entrekin set this non-performance goal before UTMB, a 108 mile race around Mont Blanc where she ultimately finished 2nd.

Not a pace or a place.

You can want a running goal SO badly that somewhere along the way, the goal stops being something you’re pursuing and starts becoming a measure of who you are.

Your kid gets sick and you miss Tuesday’s intervals and instead of accepting one missed workout, you’re calculating where to squeeze them back in because you’re losing fitness.

Your plan says 8:00 pace should feel controlled, but today it’s 8:17. Instead of considering heat, sleep, stress or accumulated fatigue, you decide something is wrong with your fitness.

Your training partner runs 18:52 and you run 19:14 … you were proud of your race until you saw hers.

Someone training for the same race posts 22 miles on Strava while your coach prescribed 17 becomes “Am I doing enough?”

You nail only 5 of 6 reps so you spend the cooldown obsessing over the one you missed.

You feel a ni**le 3 weeks before your goal race and instead of seeing a PT, you keep running because you’re more afraid of losing fitness than making the injury worse.

You come through halfway 90 seconds behind A-goal pace, but instead of competing for the best race still available to you, you decide the day is over.

You miss your goal by 90 seconds so before you’ve even processed the PR you DID run, you’re searching for another race to prove yourself.

This is the dark side of perfectionism in running.

The data stops being information you can respond to and becomes evidence you use to judge yourself, and eventually your relationship with yourself becomes conditional on your performance.

I don’t want athletes to stop caring about their results.

Chase Boston. Chase sub-3. Chase the podium. Chase the buckle. Find out how freaking good you can get.

But it also matters to me you’re secure enough that your ambition doesn’t consume you.

Stand on the starting line knowing exactly what you want and know you’ll still respect the person who crosses the finish line if the day doesn’t unfold according to plan.

Sometimes success IS the PR or podium.

Sometimes it’s adapting when Plan A disappears and discovering what else you’re capable of.

I wanted this with everything I had. I gave it everything I reasonably could. And I still like myself at the end.

That’s the athlete I’m interested in developing.

I didn’t become a better coach because training always worked perfectly for me.

I became a better coach because for a long time it didn’t.

Years of navigating Lyme disease, coinfections, treatment-resistant EBV, recovery, relapses, podiums, back-of-the-pack finishes, and big breakthroughs taught me something my certifications could only reinforce:

Training is scientific. But humans are not equations.

The goal isn’t to see how much training you can survive. It’s to find the training your body can absorb, and learn when to pull back, when to stay patient, and when it’s finally time to dig deeper.

That’s especially important for ambitious runners who tend toward perfectionism. You don’t need to care less about your goals. Trust me, I KNOW how hard it is to want a goal and feel it slipping away.

You need an approach that lets you chase them without losing your health, your life, or your love of running along the way.

If you’re chasing a big goal but feel like there are a lot of puzzle pieces between where you are and where you want to be, or maybe you’ve got all the pieces but they aren’t clicking together, I’d love to help you put them together just so.

This comment meant more to me than simply seeing an athlete nail a workout. Perfection isn’t the goal; progress is.

This athlete and I have been working together for nearly three years, stringing together 5ks, half-marathons, and fulls, and the mental side of training has been a huge piece of her development.

She wants to to hit her splits.
She wants to Boston qualify.
She wants to keep chasing PRs even as a busy, full-time working mom.

Motivation has never been the problem.

But sometimes doubt creeps in and with it, the tendency to strain, force, or question whether she’s capable of what we’re asking her body to do.

And that can derail progress just as easily as not working hard enough through injury, overtraining, and mental burnout.

So when she went into this workout nervous about whether she could sustain the effort, and then told herself:

“You’re stronger than you think.”

…and executed it?

THAT is the progress I am looking for.

Not because a mantra magically made her fitter.

Because she recognized the doubt, didn’t let it dictate how she ran, stayed composed, and allowed the fitness we’ve spent years building to show up.

This is such an important part of coaching ambitious athletes.

Often, my job isn’t convincing you to work harder.

It’s teaching you when to trust yourself enough to stop fighting your own fitness and just let the effort BE.

The physical and mental pieces of performance aren’t separate.

We’re training both.

Do you have a big running goal you want to achieve? Are you willing to learn how to fight the monkeys off your back and actually believe what you’re saying to yourself?

Comment WILLING, and I’ll message you to see how I can help you with your next big goal!

You want to find out how good you can get without burning yourself out to get there.

You want to break 20 minutes in the 5K.
Qualify for Boston.
Finish your first marathon with a smile on your face.
Run 100 miles.
Complete a pull-up.
Stay healthy enough to train consistently.

But running isn’t the only thing you do.

You have a demanding, rewarding career. Kids with late night activities. A partner you don’t want to make a marathon widow of. Travel plans that aren’t also a runcation. Board meetings and doctor appointments. Aging parents who need you. Weeks when everyone in your house seems to need something at the same time, and your needs come last.

And yet somewhere in there, you want to feel good too.

You want enough energy to show up for your life and your training.

Getting better isn’t just about what mileage you can handle.

In order to do that, you’ve got to figure out the puzzle and ask the right questions:

How much should you run?
When should you push, and when should you back off?
How does strength fit in?
Are you fueling enough?
Are you recovering?
What happens when work explodes on the same week your plan says 50 miles?
What do we change when something starts hurting?
How do we keep building when life inevitably interrupts the build?

There are so many puzzle pieces.

That’s where high-touch coaching comes in.

I’m not handing you a training plan and disappearing until next month.

I’m paying attention to the whole picture with you.

We adjust. We troubleshoot. We learn what your body responds to. We make decisions based on where you are now while keeping sight of where you want to go.

Sometimes I’m pushing you forward.

Sometimes I’m reminding you that doing less today is what allows us to do more six months from now.

And sometimes we’re completely changing the goal because life changed.

The goal is to help you become a stronger, smarter, healthier athlete who can keep finding out just how good you can get.

I am always looking to serve athletes who want to see how good they can get and are willing to learn, adapt, and play the long game to find out.

Comment “CURIOUS” if my message aligns with you.

08/23/2026

So much of the conversation is about everything you should do before you have kids, or all the freedom you have if you don’t.

But motherhood didn’t make my life smaller.

Maybe I can’t disappear to Chamonix right now for a month and spectate UTMB.

But I can still have big adventures.
I can still chase big goals.
I can still keep becoming.

Tour du Mont Blanc.
100-mile podiums.
Boston.
3:04 marathon.
19-minute 5K.

I did all of it after becoming a mom.

14 years later, I’m still growing and developing as an athlete, and my girls are watching.

My life isn’t less adventurous because I have them. It’s richer. More purposeful. And we’ve grown through it side by side.

The best is yet to come! 🧚‍♀️✨

AI isn’t coming for good coaches.

It’s raising the bar for what good coaching needs to be.

I actually coach an athlete who used ChatGPT to guide his training before working with me. And in recent weeks, he’s repeatedly shared how grateful he is to have the knowledge, context, feedback, and guidance of an actual coach.

Not because AI gave him bad information.

Because information and coaching are not the same thing.

ChatGPT can give you a workout.

It can explain training principles. It can build a progression. It can suggest mileage, long runs, workouts, fueling strategies, strength work and recovery.

What it doesn’t have is the lived relationship with an athlete that allows a coach to recognize:

This workout says one thing, but everything I know about you tells me we need to do something different today.

That distinction becomes especially important in endurance running, where two races of the same distance can require dramatically different preparation.

The example in this carousel happened this morning: an athlete who was pulled at mile 55 of a mountain race last year has since completed 66 miles at a backyard ultra.

Those numbers alone don’t answer whether she’s ready to return.

They give me better questions to ask.

That’s where experience, course knowledge, athlete history, pattern recognition, communication, and judgment come in.

But if an athlete assumes an entire coaching service can be replaced by asking ChatGPT for a training plan, the problem probably isn’t AI.

The standard for coaching has simply gotten higher, and I think that’s a very good thing.
