Visited 76 Harley Street, a medical practise specialised in serving elite and extreme athletes, including those pursuing high altitude expeditions.

Had a pre-expedition health check with Dr Jack Kreindler.

Returned to 76 Harley Street in the evening for a CPEX (Cardio-Pulmonary Exercise) test, administered by Jim, an American biochemist who used to date a girl from Kokkola in Finland!

Dr Jack will be comparing my resting data points to data points measured during and immediately after the resistance test, in which a computer is steadily increasing the resistance of the exercise bike.
