Took a bit of time out after the half marathon, climbed snowdon though. Back on it again now and got my 5k down to 21 minutes and my 10k down to 44. Think I need to back off a bit now though and concentrate on distance as I've entered the Stafford half marathon in March Anyone got any tips for running in the cold? Tonight my breathing was quite laboured and my throat is a little sore, it's also hard to work out what to wear because a slight change in pace seems to equal a huge change in temperature. Currently wearing long sleeve cycling tops so I can open the zip if too warm and roll up the sleeves. EDIT: I also got a HRM strap, but I think my heart defect is making it play up. Its fine at rest but when I start to run I hit about 175bpm within the first few minutes then stay between 170 and 180 all run. For my age thats pretty much the maximum I should be able to go and there is no way its sustainable, so it must be reading wrong.
