Chip Finish Time: 3:32:08
Goal: Sub 3:30
Gap: 2 minutes and 8 seconds

As a sport psychologist, I spend my professional life helping athletes navigate the mental challenges of competition. I teach strategies for managing pressure, reframing setbacks, and maintaining focus when the body screams at you to stop. But on race day at the Southampton Marathon, I found myself on the other side of the conversation, not as the advisor, but as the athlete needing every psychological tool in my arsenal.

The Goal and The Gap

Two minutes and eight seconds. In the grand scheme of a 26.2-mile race, it's almost nothing. Yet it represents the difference between achieving a goal and falling just short. The sub-3:30 marathon had been my target for weeks of training, a number that represented not just fitness, but a benchmark I'd set for myself.

Crossing the line at 3:32:08, whilst my immediate reaction was celebration and relief, it was also a slight sense of disappointment. And isn't that interesting? I'd just run 3 hours and 32 minutes at a pace I was still incredibly proud of, yet my brain still went to what I didn't achieve rather than what I did.

This is the kind of mental trap I support clients with daily. Yet I was falling into it myself.

The Hill That Tells the Truth

If you've run Southampton, you know the hill I'm talking about. For those who haven't, let me paint the picture, it arrives towards the end of the both laps, at a point where your glycogen is depleted, your legs are heavy, and your mind is searching for reasons to slow down. It's not Everest, but at mile 23, it might as well be.

The first time up, during lap one, I handled it well. I'd conserved energy, maintained my breathing rhythm, and reached the top without significant time loss. I remember thinking that I'd managed it well.

But the second time? That's when the marathon distance started to take it's toll.

The Psychological Battleground

As I approached that hill for the second time, I could feel the doubt creeping in. My pace had already started to slip. My brain was doing calculations: How much time do I have in the bank? Can I still make it? What if I push it and blow up here?

This is where sport psychology theory meets the reality of endurance racing. In my sessions, I talk about:

  • Attentional focus: directing your mind toward productive cues rather than pain or negative thoughts

  • Self-talk: using constructive internal dialogue to maintain effort

  • Process goals: focusing on controllable actions rather than outcome pressures

But at mile 23, with that hill looming and my sub-3:30 slipping away, those concepts felt abstract. The psychological strategies I teach aren't magic, they're tools that require energy to implement. And energy was the one resource I was running low on.

When the Mind Wants to Negotiate

Here's what I experienced on that second climb, and what I know many of my clients experience in their crucial moments:

The Bargaining Phase: My mind started offering deals. "You can slow down just for this hill. You'll make it up on the downhill." (Spoiler: there wasn't a downhill.)

The Rationalization: "3:32 is still a great time. Does two minutes really matter?" (It did. I'd set the goal for a reason.)

The Catastrophising: "Your legs are going, keep pushing and you're going to blow up."

I recognised these thoughts for what they were, the brain's way of trying to reduce discomfort. But recognition doesn't make them completely powerless. This is the honest truth I want to share: even knowing the psychology doesn't make you immune to it.

What Got Me Through (And What Didn't)

I tried to implement my own advice:

Breaking it down: I stopped thinking about the top of the hill and focused on the next 20 steps. Then the next 20. This helped.

Reframing the discomfort: I reminded myself that everyone around me was suffering too. That the pain and heaviness was part of the process, not a sign of failure.

Positive self-talk: I cycled through phrases emphasising "You've trained for this," "Keep the effort." Something I should have practiced within training for true effectiveness.

The reality? I reached the top that hill slower than I wanted. I lost seconds that I wouldn't recover. My sub-3:30 goal felt impossible on and after that incline, along with the heavy breathing and burning quads.

The Finish Line and Beyond

Those final three miles were an exercise in damage limitation and management. The goal had shifted from "achieve 3:30" to "minimise the damage." I crossed the line with a chip time of 3:32:08, exhausted.

But here's what I've learned in the days since, and what I want my clients (and myself) to remember:

The marathon is the one of the most honest psychological assessment you'll ever take. It strips everything away and reveals how you handle adversity, disappointment, and physical discomfort. That hill, especially the second time, was a mirror held up to my own resilience.

Knowing sport psychology and applying it under duress are different skills. I can explain cognitive reframing in a workshop, but implementing it at mile 23 with depleted glucose and aching legs? That's a different challenge entirely. This experience has made me a more empathetic practitioner.

Goals are targets, not identities. I didn't hit sub-3:30. That doesn't erase the months of disciplined training, the early morning runs, or the fact that I ran 3:32:08. The slight disappointment is valid, but so is the achievement.

What This Means for My Practice

This experience has reinforced several truths I'll carry into my work:

  1. Psychological strategies require practice under pressure. We can't just learn them intellectually, we need to rehearse them in progressively challenging situations.

  2. The moment of truth reveals preparation gaps. That second hill showed me where my mental training needed work. Every athlete has these revealing moments.

  3. Process over outcome works, but it's hard. When I focused on my form, my breathing, my current split, I performed better than when I obsessed over the final clock. But maintaining that focus required constant effort.

  4. Failure is data, not definition. I didn't achieve my goal, but I was close, and gained insights that will inform both my training and my professional practice.

The Hill Remains

The Southampton Marathon course hasn't changed. That hill is still there, waiting for next year's runners. It will test them the same way it tested me, not just physically, but psychologically.

For those preparing to face it, or any similar challenge in your own racing:

  • Respect the second lap. Mental fatigue is real and cumulative.

  • Have flexible goals. Know your A, B, and C goals before race day.

  • Practice suffering. Do training runs that hurt, that challenge you mentally when you're tired.

  • Prepare your self-talk in advance. Don't wait until mile 23 to figure out what you'll say to yourself.

  • Remember that everyone struggles. You're not weak, you're human.

As for me? I'm already thinking about the next event. Not because 3:32:08 isn't good enough, but because I'm curious about who I'll be the next time I face that distance. What will I have learned? How will I have developed?

The sub-3:30 marathon is still out there and I'll be better prepared, not just physically, but psychologically to chase it.

Because that's the difficult truth about marathon running, it's always a conversation, or heated debate, between the body and the mind, and is exactly the reason I enjoyed it so much.
