North Downs Marathon

I’m one week in to the Maffetone two week test – eating no sugar or refined carbs. My goal for this race was simply to survive and finish, using just energy reserves stored in my body. I had water, and an emergency gel, but was not planning on eating. Unusually for a race, I wore a heart rate monitor, to try and help ensure I kept my HR low and in the fat burning zone. The plan was to keep HR at 135 – 140.

The North Downs Way between Reigate Hill and Denbies Estate is amazing. The trail alternates between sheltered woods and wide open meadows with superb views to the south over the Surrey Hills. It’s one of my favourite places to run. Unfortunately on Sunday the  it was overcast and alternating between 100% humidity, drizzle and light rain. I had my sun cream and sun glasses, but during a few of the wooded sections I really wished I’d brought a head torch as it was so dark.

Sarah and the children had decided to come with me, although their plan was simply to play around Box Hill rather than try and follow the race. Race Registration and the start and finish was at the Reigate Hill Golf club, so after getting my race bib, I had a coffee and a chat with Bryan and Conrad. At 9, Dave Ross sent us on our way. The first mile was fairly flat, so I managed to run reasonably near the front, but then in the second mile the route climbed 300ft, and I had to slow to keep my heart rate from soaring. From Reigate Hill and along the ridge to Colley Hill is flat, and then there is a steep drop down a technical track to another flat section at the base of the downs.

After six miles the trail starts to climb again, heading slowly up to Box Hill. I walked the steps up, mindful that my heart rate had been pushing up to 150, and would be burning carbs for fuel, and I had no plans to eat any in the race. The steps down the other side felt fine, but in places the chalk path was slippery I saw a couple of runners slide and fall. The race route goes over the stepping stones rather than the bridge, which is fun and makes for a good photo. My family were here to watch, and the children had been running back and forth over the stones when there was a gap between runners. Fortunately no one slipped and fell in.

The route briefly follows the A24, to go through the underpass, and then back up to the Denbies Wine Estate. It climbs 400 ft over the next two miles, but for the most part the gradient was not too bad, so I ran up slowly but steadily.  Finally I reached Ranmore Road, and then ran on a little way further to the turn around point, and began the run back.

The long downhill section through Denbies was fast and fun, but the section at the A24 was very crowded. In addition to our race there was the Badger half marathon and a cycling race, all sharing the same section of path and adjacent cycle track. Fortunately after the underpass, we had the route to ourselves again. I was starting to feel a little low at this point. My energy levels were down, and it felt like I had run much further than the 16.5 miles my garmin was showing. Normally I’d take a gel and push on, but instead I slowed down and tried to recover.

After the crossing the stepping stones again, it was now back up the steps to the top of Box Hill. Even though I walked the steep section, my heart rate still hit 152 here.

The run along the top of Box Hill was fun, as was the descent, but after crossing Buckland Lane at 21 miles I had to slow down again a few people ran passed me. The last big climb up to Colley Hill was slow and painful, and my right hip and glute were causing some pain, but with only 3 miles left now I was nearly done, so pushed on to Reigate Hill and then the drop back down to the golf club and the finish line. At the finish

My time (4:21:51) was largely irrelevant. I’ve been starving myself of carbs all week, and my body has not yet adjusted to this new regime, so I was just glad to finish. I did feel a little wobbly after the race, but fortunately they were serving food at the golf club, and after an omelette and salad I was feeling much better.
