With only a few days to go before Kilimanjaro, we were extremely lucky to be able to get to use the altitude chamber at St Mary's University in Twickenham. We managed to get up to the equivalent of 4500m in terms of oxygen percentage in the air. It felt really good! we did a full hour and 30min of running at a steady pace and felt no side effects which made us a little more optimistic about the 5 day trek on Kili. Thanks St Mary's for giving us that lovely opportunity!
