Phew! I went as slowly as I could and still needed my inhaler. So glad I can put my feet up now!
Trying not to worry about week 4... 5 minutes sounds like a long time when 3 minutes left me breathing heavily even though I jogged slower than I normally walk.
On the plus side, a little old lady gave me a thumbs up when I "ran" by her earlier which made me beam like a crazyperson!
