3 weeks to Berlin: Last of the long runs

This was the last of the big mileage weeks in the run up to Berlin and the training plan had popped in a sneaky load of short, sharp intervals just for good measure.

With a bank holiday on the Monday, I took the opportunity to slip in my first outing on the road bike, since returning from France. A few weeks off the bike had had a noticeable effect and the legs felt nowhere near what they had been. I guess it was to be expected really, my cycling thighs have already visibly reduced, since piling on the running miles and leaving the bike at home. I can't stop being amazed at how quickly your body can transform, when you improve your regularity and turn up the intensity of your running. Everything starts to slim down as your body starts to tell you, "you won't be needing this, and these can definitely go and, while you're about it, you may as well have a haircut, don't leave anything to chance!"

It was good to have been back on the bike, but this month is all about running, we're only 3 weeks away now, so of course it is. So back to those intervals...

Ten reps of any running sounds, well, repetitive and, probably quite tiring and time-consuming. It wasn't so much the fast bits that worried me, but the recovery runs were at a steady pace and with those and the warm ups and cool downs, this was going to be anything but quick for a mid-week, post-work, post-kids going to bed session.

The other worry was that the last time I'd run 400m at pace, I unsettled an old injury in my lower back. It had taken me 6 months of rest and gentle running to get back to full strength and I wasn't keen on popping my back with the marathon in clear sight. Fortunately, the pace wasn't too full on and my core strength is much improved on what it was when I injured myself, a little over a year ago, so I came through unscathed. The session was repetitive, obviously, but intervals always feel quite rewarding and like you're forcing a real change to the physiology of your body, at least that's what I convince myself.

Thursday night's marathon pace run was tiring, I'd cycled 30km the day previous, to get into work and back and so hadn't had much rest between this and Tuesday's intervals. I got myself through it by remembering that, on marathon week, I'll be mostly resting and not doing back-to-back exercise and that this was why I was finding the pace tough going.

The same mind tricks had to be used for Saturday's 20 mile session, this was always going to be the toughest training run, 20 miles at 15 seconds per mile over marathon pace. I'm not going to lie to anyone and pretend that the last 7 miles didn't hurt. But that's just it, a half-marathon feels relatively comfortable, anything more starts to put real strain on your body, that's the challenge of the marathon, it requires dedication to training over several months to reach the form you require. If you're going to run it, that is. For one, once you've run for more than 2 hours straight, you've burnt off your body's natural store of glycogen, running beyond here is uncharted territory for your body and the point from which you have to keep taking on more fuel, or you'll drop. Getting this right, both in terms of what to take on and when, can be key to maintaining a level head and keeping the negative thoughts at bay. I've not figured out the perfect balance just yet but, through experimenting with different gels, bananas and sports drinks, I'm building up a reasonable picture.

Whatever I did, I managed to get through the training run at a pace just marginally slower than race pace, and felt I had a couple more miles in me. Without a week's worth of back-to-back exercise the preceding week, surely those extra 4-5 miles are within reach.
