I'm really struggling in the cold weather. As long as I'm just walking fast I don't get an attack but as soon as I start running, however slow, it comes on. I take reliever before running and as soon as I feel it coming on but to no avail. I've tried warming up slowly as well, walking for 5 mins first then interspersing walking and running for a bit before running properly. Any tips at all? I've signed up for a fun run and I really want to be able to run the whole thing or most of it.
