Another Marathon Won't Fix Your Performance

"If you keep signing up for marathons, I'm no longer going to coach you."

I held my nerve and kept eye contact.

Rosie knew this conversation had been coming. The last marathon broke her.

For two months post-event, Rosie's energy levels were as low as her mood. Both had been left on the road in Berlin, around mile 21.

Rosie is the most disciplined person I know. Highly successful. Highly ambitious.

But getting out of bed had become a brutal duel between mind and body. Her nervous system lay dormant, refusing to move.

Rosie's deep-rooted need for validation by numbers had pushed her body a step too far.

As armoured as Rosie looks on the outside, there's a quiet hum of self-doubt on the inside that she will never be good enough.

Rosie has dealt with this her whole life, always feeling doubt when others feel pride.

This plays out in Rosie's running.

It can show up as ambition.

But ambition can only outpace capacity for so long.

And that's what got us into trouble.

I say "us" because, as her coach, I take responsibility. I didn't push back hard enough when she told me she'd secured a place in Berlin.

The year before, in London, we missed a PB by two minutes.

It didn't matter that Rosie trained like a rock star during one of the most stressful periods of her career.

Wind. Rain. Last-minute business trips to Belgium. Rosie did the work.

Even in the final training cycle, when she was stuck at her desk on weekends, we recalibrated training load versus workload. Her numbers on the track and in the gym still looked good.

Those two minutes were not down to Rosie. In my eyes, she did everything spot on.

It was simply the cruelty of the running gods.

But Rosie doesn't see grey. Those two minutes were her failure. And that needed correcting.

Berlin.

I said no at first.

I've worked with Rosie for five years. I've seen how increasingly difficult it's become to balance training demands with the demands of life.

With so much of her identity tied to racing, the emotional toll was just as heavy.

At the time, we needed to step back.

We needed to build the systems that would increase her overall capacity to handle stress.

There are no quick fixes. It would take at least a year.

But Rosie had unfinished business.

And as hard as I tried to sway her, we were going to Germany.

Let me be honest.

I knew what the outcome would be.

I'm not psychic.

I just know when an athlete is unable to calibrate stress and recovery for the adaptation they want.

Especially one I've worked with for so long.

They're going to burn out or get injured.

Nervous systems crash into a state of dysregulation that can take months to recover from.

At first, bodies feel wrecked. Then the mind follows with 4 a.m. wake-up calls full of anxiety about the day ahead.

The friction I manage is between my first priority, keeping my clients safe, and Rosie being an adult capable of making her own decisions.

Ultimately, I presented my case and chose to support her goals.

Yes, I'm nervous.

But I'll let you into a coaching secret.

I'm also a little bit happy.

Rosie needed to get a little burned by the heat of Berlin. To second-guess getting so close to the fire when underprepared.

I battle with this process as a coach and as a human.

Am I avoiding harder boundaries because it's uncomfortable?

Rosie's eyes broke contact with mine. They dropped, then came back up.

"Okay. I won't do Copenhagen this year. We'll go back to the foundations. But in 2027, I want that time."

I nodded.
