Report on Monday night training - I ran about 40 laps of Parliament House car park, owing to the non-clement weather outside. On arriving home afterwards, I did a few moments research on the affect carbon monoxide can have. "Carbon monoxide (CO) binds to haemoglobin with a higher affinity (200x greater) than oxygen, and at the same binding site. Consequently, carbon monoxide will bind haemoglobin preferentially over oxygen when both are present in the lungs - even small amounts of carbon monoxide can dramatically reduce the ability of haemoglobin to transport oxygen. Levels as low as 0.02% carbon monoxide can cause headaches and nausea, while a concentration of 0.1% can lead to unconsciousness. This accounts for the suffocation caused by carbon monoxide fumes, such as from the exhaust of a car engine." All of which convinces me we might run in the rain next time, instead of in the underground car park... even when it is raining cats, dogs, ducks and geese.

Late entries will be taken on the day. But so far, ten of us are having a go.
