Testing of Krispy Kreme Formula v.1.0
(i) Test One - Mountain biking - 40km
Per my Garmin, calories burnt = 1,563
Injuries = none
Terrain = muddy track, slippery leaf-strewn paths for c. 70% of the route. Tarmac for the rest.
1,563 x 1 x (1.9 x 70% + 1.0 x 30%)
= 2,597 calories
= 13 regular glazed ring doughnuts or 7.4 filled doughnuts
(ii) Test Two - Orienteering - 12km
Calories burnt = 793
Injuries = gorse splinters, two large blisters (presumably I would be allowed to count both injury scores? That would be 1.5 for the blisters and 2.4 for the splinters)
Terrain = sandy paths, heath, woodland (I would equate this to tufty grass, 1.3)
793 x 3.9 x 1.3
= 4,021 calories
= 20 glazed ring or 11 filled
My initial thoughts are that these numbers are coming out a little high. I am also concerned about the efficacy of the Garmin for measuring calorific output. It felt like much harder work running 12k than it did cycling 40k. Perhaps further refinement is required...
