It does depend when with in the run you get this. I get it within the first 20 mins. This is just the warm up process. It should settle down as you get in to your run this should normally settle at around the same time your breathing settles down.
Hi All, I was a bit confused when I got my race pack today. It allocates you a colour which is your start time. The thing is my wrist band is yellow, there is no yellow on the list !!! The booklet sayes it the background colour not the colour the number is printed. Does anyone no if I'm looking at the wrong thing?
