Getting high

Out of sheer desperation, conscious of the 3,000m altitude of some of the mountainous roads on the RAAM route, I decided to have a go at using Intermittent Hypoxic Exposure (IHE) to get my body acclimatised to working at altitude. I visited The Altitude Centre in central London: the entire room had a reduced partial pressure of oxygen, equivalent to approximately 2750 metres above sea level.

 

However, with IHE I was alternating for an hour between this rarefied air and a mask with even harder to breath air with less oxygen, equivalent to approximately 4,500 metres above sea level. The session was not at all pleasant, and reminds me that altitude is just one of the many ways in which we shall all suffer on RAAM!

 

In order to derive any real value, I’d have to do several more IHE sessions, but given the proximity to my flight out to the States, I think I’ll focus on the cycling instead!
