At the end of that road, at the Place de la Porte d’Auteuil, we took a ninety degree turn onto the Route des Fortifications – which was a mild incline. Any incline at this stage, some 37kms (or about 22 miles) in is unwelcome though. Running with the pacemaker and running in a group of other people, really helped at this point. Not only was the pacemaker shouting encouragement (in French, of course) but at this point in my previous marathons I’ve usually found myself virtually alone, which saps your resolve. Keeping up with the pacemaker and the group helped me keep on track when I know that, had they not been there, I probably would have slowed down and fallen back at this point.

About a kilometre later the course entered the final phase in the Bois de Boulogne, another huge park. We took another turn onto the Chemin de Ceinture du Lac Supérieur. This was probably the hardest part of the race, not least because it was the last few miles, but also because there were relatively few supporters around this section and the tremendous strain on my legs was now impossible to ignore. I wasn’t just tired, I was getting that achy feeling where when you stop running for any reason, trying to get going again is twice as hard because your legs feel like lead.

The scenery had taken on a dull tone because we were running along a section of the park that was rather uninspiring and because the sun had gone in again. The only thing that broke the boredom of this section was the appearance of several marquees, set up by several different French marathons, advertising their races. Some even offered samples of local wines – but naturally, I didn’t partake. The course turned onto the Avenue de Saint-Cloud, which was another of those long stretches which never seemed to end. There were a few more people around the Chemin de Ceinture du Lac Inférieur, but it didn’t feel like we were just a mile away from the finish.

Within what seemed like just a couple of steps, we were back in inner city Paris again, running around the roundabout at Porte Dauphine, then along the wide boulevard of the Avenue Foch. When I saw the finish line a few hundred yards ahead of me, it all felt a bit sudden. It was a short distance from there to the finish. The pacemaker congratulated us all on running a fantastic race then allowed the pack to split up and run past the marathon photographers.

Finally, I crossed the finish line exactly five hours, twenty-seven minutes and five seconds after I started. Almost immediately the muscles in my legs started screaming and burning from over-exertion. I shook the pacemakers hand and had my photo taken by a defeated looking Frenchman sitting on a chair near the finish line.

Even though I completed the marathon under my target time of 5h30m and even though I beat my personal best (though only by a matter of seconds) it still felt a little bittersweet, because I felt that I could have run faster and shaved another half-hour off my PB.

However, I still stand by my decision not to try for a PB and to deliberately under-estimate my performance. This was my third marathon in less than a year, after all!

I suppose there is always next year…

Video: The final word

Once I’d eaten, I returned to my room to put on the rest of my clobber: A waist pack for carrying energy gels, an arm wallet for carrying my MP3 player (just in case I needed some musical motivation) and my race number and timing chip.

I just had enough time to do some extra stretches before I met with the other runners in my group in the hotel lobby at 7:30am. Waiting in the lobby left a few minutes to chat to the other runners. Most of the runners I talked to were marathon newbies, some had run half-marathons before whilst others had only started running two months ago – and now they were attempting a marathon! Once everyone was assembled, the guides led us out of the hotel through a subway and then we all walked down the Avenue de la Grande Armée.

A few metres before the Arc de Triomphe, where the race pens were, the guides gave us our final instructions to leave any bags in the baggage area at the finish on Avenue Foch and then to make our way to the Avenue des Champs-Élysées, where all the start pens were.

Now I had registered in the pink time zone of runners who expected to finish in a time of 4h30m. However, I have said before that I would be trying for 5h30m again this time. The only reason I registered in the pink zone was because that was the slowest group offered when I registered originally. So I stayed at the back of the pink zone, planning to fall back as soon as possible to my own 12m per mile pace, which would lead to a time in the region of 5h30m.

In the shadow of the Arc de Triomphe, I recorded my first “piece to camera”…

Start line update

At about 8:45 French time, the announcer kicked off the 2009 Paris Marathon with a very fast countdown. I discarded my plastic vest, but soon wished I hadn’t, as I would be waiting another fifteen minutes before I would be able to jog over the start line. Just walking up to the start was a tricky business – the road was covered with the plastic vests, discarded clothes and walking down the left edge of the road, where the crowd was less dense, there were hundreds of discarded half-empty bottles of water.

Even though the crowd was tightly packed, it started to thin out a little as people got to the start, as everyone wanted to jog over the start line rather than walk over it. Eventually I crossed the start line at about 8:57am (French time) and started my Paris Marathon attempt.

Right from the beginning my plan was to run at a steady 12-minute per mile pace. Fortunately for me, the Paris Marathon employs runners to act as pacemakers. Their sole aim is to run the race in a certain time. So, as I ran down the Avenue des Champs-Élysées, I kept on looking behind me for each pacemakers’ trademark flag. I felt like I couldn’t settle down into a good rhythm until I found the pacemaker – and when I passed the first kilometre marker I knew I had to slow down a lot more and that my pace was too fast.

Seeing that kilometre marker also got me worried about how the distance would be counted – France, of course, uses the metric system, where a marathon is 42.195km, not 26.2m. If the distance was only marked in kilometres, I would have to do some pretty quick mental arithmetic to work out when I’d passed each mile. Not something I wanted to do whilst running a marathon.

Finally the flag of one of the pacemakers appeared, but to my surprise it was the 5h00 pacemaker. So I had to slow down even more until the 5h30 pacemaker passed me. At the end of the Avenue des Champs-Élysées, the route turned left, crossing the Place de la Concorde, then making it’s way down the Rue de Rivoli.  I didn’t actually see much of the Place de la Concorde because I was on the outside of the pack of runners, so I couldn’t see much over the top of them. Then the course continued down the Rue de Rivoli. It was whilst running (slowly!) down here that I finally “caught up” with the 5h30 pacemaker group. I stayed with this group for the rest of the race.

Now that I was following a pacemaker, I didn’t need to worry about kilometres vs miles, because all I needed to do was just keep pace with the pacemaker. I was surprised just how far back the group was at the beginning, but it just goes to show how much of a mistake I could have made by getting caught in the moment at the start and by continuing at that starting pace. With hindsight I understand now that the strategy of the pacemaker was a classic “negative split” – that is, by running deliberately slower than your race pace in the first half of the race, then speeding up in the second half, you can run the distance much more “comfortably” – though that’s not a word I use often when talking about running a marathon.
