I have just bought a champion base layer for extra insulation as the winter approaches.
However, I have worn it for a couple of runs (10k & 6.5k) and found it quite tough to breath properly when tiring (before anyone says it, I am sure I have bought the right size) I have taken a couple of views on this:
1) Bin it as it isn't doing me any good....
2) Keep going with it, on the basis that it will help strengthen my breathing so when I race & don't wear the under layer the theory is that I will find it easier...
Just wondered if anyone had any views?
Thanks for looking.
