I always have two puffs on my inhaler about 15mins before setting off and then use it as much as I need, even if I just feel a twinge of asthma coming on. I always try to breathe deep into my stomach (so your stomach moves in and out when you breathe) in a steady rhythm - helps get air in and stops any sense of panic, which only aggravates my asthma.

I also always breathe through my mouth - gets more oxygen in and out. I also really force the air out hard and loudly, to keep any asthma in check. I know I probably sound like I'm heavy breathing when running but, hey, if it gets me to the finish line, so what?!!

Much of my breathing technique has been built up after years of hiking and climbing mountains. I haven't run in the cold yet but as and when I do I'll do what I do when hiking - wear a buff (like a scarf/cowl) around my neck that I can pull up over my mouth to breathe through as the cold air always sets my asthma off.

I've also had a meds review in the last year and have gone on a preventative steroid inhaler and a tablet to stop nasal drip (Singulair - the drip has been irritating my lungs). Now I'm getting more active I'm not prepared to put up with wheezing any more!

And, of course, the increased fitness has had a marked effect on my asthma. I now have a lung age of someone six years younger, which I never thought would be possible.

Keep at it and we will all be cheering you on!

You too! Can't let it beat us!
