I Ran the Manchester Marathon on One Day Notice

The Phone Call

The evening of 26 April 2025. A phone call from a mate — he was ill and could not run the Manchester Marathon the next morning. Without thinking, the words came out: "Yeah, I will take your place." Zero marathon-specific training. The longest run to date was the Wilmslow Half five weeks earlier. Nothing beyond 21 kilometres. Ever.

Wilmslow had gone well — 1:38:17, smashing the sub 1:40 target with room to spare. But a half and a full are completely different animals. Everyone knows this. Choosing to ignore it felt easier than acknowledging it.

The Night Before

The evening was spent frantically Googling marathon nutrition strategies and laying out kit. Gels beyond 15 kilometres? Never tried them. Drinking water at pace? Never practised. The entire strategy boiled down to: start slow, do not die.

The alarm was set for 5:30am. Sleep was almost impossible. Excitement, nerves, and the growing awareness that this was a monumentally stupid decision kept the ceiling interesting until well past midnight.

The Start

Race morning at White City was surreal. Thousands of people who had spent 16 to 20 weeks training for this moment. Many with pace bands on their wrists and detailed nutrition plans. Meanwhile — a banana and blind optimism.

The weather forecast said sunny and warm. Not ideal for a first marathon, especially an unplanned one. A spot towards the back seemed sensible. Run by feel, not by pace.

Miles 1-13: Surprisingly Good

The first half went better than anyone had any right to expect. The flat course through Stretford and Sale felt comfortable, and the crowd support was incredible. An easy pace, trying to enjoy the experience rather than worry about the finish.

The half marathon point came and went. Everything felt fine. But every bit of running advice says the same thing: a marathon does not really start until mile 18. Everything before that is just the warm-up.

Miles 18-22: The Wall

They were right. Around mile 18, legs started to feel like they belonged to someone else. Nothing in training had prepared for this. Half marathon fitness got through the first 21 kilometres, but everything after that was uncharted territory.

The temperature was climbing. Two aid stations involved walking. Dropping out at mile 20 crossed the mind more than once. But the crowds were incredible — strangers shouting encouragement, handing out jelly babies, holding signs that said things like "You are not nearly dead yet."

The Finish

Turning onto Deansgate for the final stretch was the most emotional moment of the whole thing. Exhausted, sunburnt, running on pure stubbornness. The clock read 4:11:08 at the line. Not fast. But for someone who decided to run a marathon approximately 12 hours before the gun went off — acceptable.

Medal collected, foil blanket wrapped, sat on the pavement for about 20 minutes. Legs did not work properly for the next four days.

What Came Out of It

Do not run a marathon without training. Seriously. This worked out because of a decent half marathon base and sheer stubbornness. But the recovery was brutal and recommending it to anyone would be irresponsible. That said — sometimes the best experiences come from saying yes to something stupid.

Training for the 2026 Manchester Marathon is underway now. A real training plan this time, proper nutrition strategy, and a goal time that does not involve the words "just finish." The marathon is 19 April. This time — ready.
