so far I've covered 2 x 408 meters, 485 meters 495 meters 490 meters, 480 meters, all have been done off oxygen and sats normally drop down into the high 60s.
Every time I go I joke with the nurse saying this is the one where I break that 500 meter barrier but it does seem just out of my reach, as ever the eternal optimist in me is saying tomorrow will be the day.
come on dall you can do it!!!
