This is the pre-run post that will inevitably be followed by a post-run post. The North Shore Marathon is on the coming Sunday and out of the four different events I've run, it is the one that has been hardest to crack. I feel I've never done it well. Even the best time, my effort in the cancelled event of 2019, was still a crawl to the end (and then a finish line vomit). I've vowed this year would be my last attempt (at least for a time) and next year I should try some that I haven't tried before.
Why is this course hard? Even though it is simply running back-and-forth, back-and-forth between Milford Beach and the top of Northhead, it has 12 beach sections (four times doing the same three sections), 10 hills (including Northhead twice, and with 500m ascent over the whole course) and all this spread out over the normal 42.2km of a marathon in between.
Another element is the placement of the second ascent of Northhead, which starts at the 30km mark. For those who haven't trained and run a marathon before, the rarefied air beyond 30km is when the "Wall" lurks. Even on the flat, you can feel like a champion at 29km, hit the Wall and then uncontrollably slow at 31km. Last year I mildly slowed down at 28km, and then was crawling after my second time up Northhead. In 2019, my best year, the Wall started to hit at 32km, just after Northhead, and that is still with three other hills and three stretches of beach to run over the last 10km. Any strategy for running this course has to be to fuel well for the race and pace so that you still have enough in the tank on the descent of Northhead.
But these weeks leading up to the event I had to ask myself what my purpose was in running the North Shore Marathon. This is a very good question - and it might surprise some that many people don't "race" to do their very best. This is not the course for a Personal Best, and it's not an "A-race" for me (i.e. the main targeted event), so it makes sense to think about what running it can contribute to my running and a base for other events. And as it may well be the last time running there, I like the idea of just posting a solid time, better than the previous efforts, but not risk trying to do a maximal effort, which could result in me pushing too hard and suffering yet again on the final 10km. I believe I should be able, with a maximal effort, to get close to 3:10km, and if it were the last marathon I were to ever run, I'd aim for a time in the range of 3:10-3:15, but I think 3:15-3:20 is safer, and be happy to fall back to 3:20-3:25, which would still be a course PB.
It's been an awkward period of training since the Kirikiriroa Marathon in June. I had four little enforced training breaks. Firstly, post-Kirikiriroa, I had an irritated quad which took some time to go, then almost as soon as it had come right, I had a gastro infection, and not long after that a touch of ITB syndrome, and then finally, just when I was on what was meant to be my longest run in the peak of peakiest weeks, I had a hamstring niggle again. But even with these, I have trained and run pretty well since then and there have been sessions where it is clear I am at least as strong as I am from the first half of the year.
Anyway, I'm looking forward to this run and seeing what my new fitness can do with this tough nut!
