Was supposed to run 27km today and test ‘hydration and fuelling’ strategies. This after a ‘technical’ session of 45 sec hard climbs yesterday in the Parc de Sceaux (photo). Lost some time because of the ‘switchback’ character of the coulée verte south and north from the Parc de Sceaux, and had to make today’s run a little shorter (24.8km) Discovered the power of the ‘cherry bomb’ for refuelling after 1 hr 50!
