Day 74 – Threshold Run Trudge

The Burning Cold
It was back to the grind this morning with the dreaded threshold run. The air still carried that late-winter bite, the kind that burns the lungs on the way in and somehow manages to do it again on the way out, just for good measure. There is something uniquely unpleasant about cold air at this time of year—it has all the crispness of a bright spring morning but none of the warmth to go with it. Every breath felt like inhaling liquid nitrogen while my legs did their best impression of reluctant statues.

As I descended Shorts Way down to the Rochester Esplanade, I had to work hard to keep my heart rate up, which is ironic, considering how eagerly it tries to spike when I see the alarm clock in the morning. At this hour, my body is deeply offended by the concept of speed. Every fibre of my being clings to the idea that nothing should move quickly before the sun has made a proper appearance. But marathon training doesn’t care for such sensibilities, so I pushed on, lungs burning, legs protesting and my brain quietly filing an official complaint.

Running Through Treacle

There’s something about those early morning runs that makes even the most straightforward incline feel like an impromptu geological event has caused the road to double in height overnight. As the gradient shifted, my pace responded in kind—though "responded" is a generous word. It was less of a shift and more of an outright rebellion, like my legs had entered into negotiations with gravity and reached a rather one-sided agreement. The sixteen-minute effort segment loomed ahead and I dug in, despite every part of me suggesting we abandon this foolish endeavour in favour of a warm beverage and a considerably less ambitious form of movement.

It’s remarkable how distance can stretch when you’re running uphill. What was surely a modest incline last night had, by morning, transformed into something that wouldn’t look out of place in a mountaineering handbook. Each step forward felt like wading through treacle—except without the pleasant smell, the interesting texture, or indeed any of the redeeming qualities of treacle. Yet, somehow, I made it to the top and continued my trudge towards The Math School, knowing that the hard work of today would make race day feel, if not easy, at least survivable.

The Temptation of an Extra Hour
Later, I found myself discussing the trials of marathon training with a fellow teacher who conquered London last year. We both agreed on one thing: it’s not the long Sunday runs that grind you down—it’s these midweek, early morning sessions. The ones where the bed seems to emit a gravitational pull normally reserved for black holes. Where the warmth of the duvet feels like an unbreakable contract, and the idea of emerging into the cold, dark morning air feels deeply, fundamentally wrong.

The temptation to stay in bed for just an extra hour is immense. The logic is there, whispering in the background: "You’ve already done so much… Surely one missed run won’t matter?" But that’s how the marathon wins. Not on race day, but in these quiet moments of doubt, where the true battle is fought between willpower and a particularly comfortable pillow.

That extra hour will have to wait. On 28th April, when the marathon is done, I fully intend to reacquaint myself with the concept of a lie-in. Perhaps even two. But for now, there’s still work to be done, miles to be run, and hills to be begrudgingly conquered.
