Went for another run last night. Same as last time, 5min walk, 5min run, twice. It’s surprisingly taxing on my lungs. I was breathing quite heavily after the 5mins, whereas I was fine all during the 1hr 17min bike ride on Tuesday even though I was moving at a pretty quick pace. I also don’t remember being this out of breath while running on the treadmill before. Maybe it’s something to do with running outside. Maybe I’m running too fast since I’ve no way of guaging my speed. It feels like I’m just going fast enough to ‘run’ as distinct from ‘loping from side to side’.

B: 33.5km – R: 4.4km
