Dry winter and carbon monoxide free

Chart of the session (from the 23rd Nov) was a cadence plot, which maxed out at 195rpm at 646W.
Bought a dehumidifier, which has a carbon filer in, to try and dry out the shed a bit as I have been sweating in it for a few weeks and it seemed to be getting a little unhealthy. The moisture was causing problems as it was starting to cause everthing to rust withn a week and it was always a little stuffy. So, plan 1 (after opening the door) was to see how much water would be taken out over the space of a week.

The dimensions of the shed are 5m x 4m (ok, not quite the ordinary size) with a pitched roof, which gives a volume of around 42 cubic meters and so far around 10 litres of water (in 4 days) has been taken out. Considering I was adding around 0.5 - 0.75 litres per hour this is getting near to a months worth of water, although I think there is a bit more to go yet.

This then got me onto thinking about altitude training in a slightly different way, due to the active carbon fiter and how they are used in confined environments (for removing / scrubbing carbon monoxide). My thought was in the space of 2 hours, if you do not open any door or window and excersize at say 75%, how much of a decrease would be seen in the oxygen level ? If you can remove the carbon monoxide and filter out any other bits in the process then you should be able to simulate a session from sea level to as high as you want (providing you don't pass out).

Training so far seems to be progressing well and even better after getting rid of a slight cold / cough that was doing the rounds in the office and train. This next week will be some steady hours on the trainer, ready for some good rides and miles over the chistmas break. Consistency and steady progress will continue to be the focus for now, but may go to pot if the weather is nice as I'll try and get out each day (as long as it does not cause any arguments !)
