A Hot and Heavy Experience at Oppegårdmila 2018 10k

I am lucky enough to be situated in an area with a large variety of races on offer, both locally and regionally. Oppegårdmila is a trail race of the former variety, taking place just a short few kilometres from my house. As the date for this race coincided with the final tune-up race in my marathon training schedule, running Oppegårdmila 2018 was a no-brainer.

Even if I had not participated in this race before, I have done quite a bit of running in the area of the course, so I felt familiar enough with the 5k loop that those of us who were signed up for the 10k got to run through twice. The heat wave which had half of Norway sweating over the past three weeks still hung around as the day of the race approached, and it became apparent that the race was going to be a hot experience.

Still, I think most people, including those associated with the race, had hoped that it would be a little cooler than the 31 degrees Celsius the temperature gauged showed as the gun went off. The local running scene didn’t let the heat dissuade them from participating, though, and around 200 people lined up to race the 10k.


I drove to the starting area of the race, together with my number one cheerleader. That is my wife, of course, who had once more volunteered to snap some photos in addition to her cheering duties. Despite the heat, I opted for a bit of a warm-up and ended up doing a couple of kilometres of light jogging, in addition to a few strides to get going.

While the main focus of this race was to get a good session out of it, I had been targeting a sub-39 finish time. That might sound unambitious given that I ran a 36:57 10k a couple of months back, but this is a completely different race. For one, the course is actually certified at 10 298 meters, so it’s quite a bit longer. Additionally, the race is mostly on trail, and with about 150 meters (492 ft) of climbing, it’s not really comparable to a quick road race. The heat was a bit of an unknown factor for me, though, and I had no idea how much it would affect my time. Instead of focusing too much on time, I decided to run more based on feel, to avoid a blow-up and make sure this was a decent experience just two weeks out from my big goal race.

A good few of the runners, especially those who lined up at the front, opted to run only in shorts. I remembered reading that a singlet can actually help you stay cool when it’s as hot as this, so I decided to wear one. Right before lining up at the starting line, I soaked myself in cold water, and I definitely think wearing a soaked singlet allowed me to retain the coolness of the cold water a bit longer.


0 – 3k

As the gun went off, I immediately tried to find a spot in a pack. After about 500 meters or so a sizeable gap had already opened between the pack I was in and the one ahead, and I felt that my pack was running just a tad bit too slow for me. So I set out on my own, but instead of burning a lot of energy to try and catch up to the group ahead, I just upped the pace a little.

About 1 500 meters in, I caught the first guy who dropped off from the group ahead, and I went right past. We were now properly climbing, and I felt pretty good as I was gaining on the group as well, without expending too much energy. That group was about five guys big at this point, and they probably pulled away from me a bit again on the third kilometre, as they sped up more than me on the flats and downhills.

As we started out on the fourth kilometre, I caught another youngster who had dropped off from the pack up ahead. He tried to hang on to me for a while but had to let me go after a few hundred meters. It sounded like he was struggling pretty hard in the heat.

The final kilometre of the loop is where you get back most of the climbing you’ve done, and it had a net drop of about 30 meters. One more guy had dropped from the now three people group ahead, and I overtook him just as we passed the halfway mark. I had no idea which position I was in at this point, but I thoroughly enjoyed passing other runners.

Going out on the second loop, I felt quite confident and thought that I would be capable of increasing the pace a bit compared to my first round. As I started climbing and struggled my way past yet another runner who had dropped from the pack ahead, I realised that a pace increase probably wasn’t on the cards today. My body just wouldn’t let me shift gears. Frustrating, and a bit of a strange feeling as my legs still felt decent, but it was probably the heat taking its toll.

The pack turned duo ahead split up during the climbing part at the start of this segment of the race. While I wasn’t feeling particularly fresh as I overtook the guy who lagged behind, I was pleased to see that I was still gaining on the final remainder of the group that I’d been chasing from the start. At this point, I still had no idea what spot I was running for, but I decided to at least give a proper go at reeling him in before the home stretch, figuring that it might be the difference between finishing inside or outside the top 10.

As I caught up to him, someone spectating shouted out that we were competing for the 7th spot. This probably made a bit soft, because I was well pleased just knowing that if I kept it up, a comfortable top 10 finish was on the cards. The guy who was now just behind me was a youngster, probably no more than 15 or 16, and I realised that the group I had spent the race picking off one by one, was probably his training mates. I told him to hang on to my back, and he’d smash all his buddies, and he answered affirmatively.

Coming up on the final descent down towards the finish line, I once more turned around and told my new running buddy that he’d get that 7th spot overall, but I’d make him work for it. Alright, he said, cockily, and more or less started spriting a few hundred meters out from the finish line. At this point, I had very little to respond with and settled into a more comfortable finish sprint to take home the 8th spot with the official time 40:05.

Crossing the line I high fived the boy who beat me, handsomely in the end and told him well raced. After that, I immediately started looking for someplace cool, as I was absolutely toasting. I had to make due with a couple of cups of lukewarm water, most of which I just threw over my head to cool down.

Despite being more than a minute off the time I had set my sights on, I was pretty pleased with my performance overall. I competed reasonably well and felt decent overall, even though I was working pretty hard throughout. It was probably not an all-out effort, but I’m confident it was well within the prescribed range for a tune-up race, and I am unsure how much of a limiting factor the heat was.
