SøenX is a 12 hour ultra race, where you run laps on a 1.8 km track around Lemvig Sø until your legs fall off or you hit the time cap. I ran for 12 hours minus 1 hour and 20 minutes of planned breaks (and 40 minutes of … well, short stops to refill juice, water and go to the toilet).

Race strategy

I decided to break the race into five rounds of: Run 20 km, rest 20 minutes and eat. What ever time remaining after 100 km, I would just run as “fast” as I can with what I have left in the tank.

Fuel strategy

Morning: (4:15) I had to drive to the location for about two hours, so to avoid a high blood sugar before race start, I went with a HUEL black shake with 20 g carbs.

Pre race: 40 minutes before start I had 100 gram oatmeal with a banana + 3 IE Fiasp.

Doing the race

Distance (km) Food IE Fiasp
20 HUEL H&S 100 gram (pasta) + 33 cl Faxekondi 2 Taking insulin here was a mistake, as my BS was already dropping and I didn’t eat much.
- 1 liter of juice Compensated for the extra insulin by drinking more juice.
30 Bun with butter and Nutella 0
- 0.5 liter of juice
40 HUEL H&S 100 gram (pasta) + 33 cl Faxekondi 0 Around 11:30 I started feeling better as my blood sugar started raising back up to 8-9.
- 0.5 liter of juice
50 Bun with butter and Nutella 0
- 0.5 liter of juice
60 HUEL H&S 100 gram (pasta) + 33 cl Faxekondi 0
- 0.5 - 1 liter of juice
70 Bun with butter and Nutella 0
- 0.5 - 1 liter of juice
80 HUEL H&S 100 gram (pasta) + 33 cl Faxekondi 0
- 0.5 - 1 liter of juice The last 20-15 ish km, the blood sugar was high and I felt great, so I decided I didn’t need more food other than a bit of juice now and then for the remaining of the race.
90-100 0.5 - 1 liter of juice 0

After the race I had a sandwich + chips + faxekondi

The race started at 7 and ended at 19.
