.....but my breathing was all over the place.
Started out well, trying a different start to my route so I went round in a big circle (with no short cuts, so I could have to do 5k including warm up and cool down walks!). Felt quite brave - running along a main road!! (usually stick to the estate or park where less people can see me!) Got to 2k, still feeling good, then my breathing started to get a little difficult. Tried to focus on breathing in through nose and out through mouth, but it was getting harder, so I decided to walk for a bit. Breathing wasn't slowing down so took a few puffs of ventolin and walked until it felt normal again. Ran for a bit more until I went round a corner and the wind quite literally took my breath away!! So walked for a but more (with a bit more ventolin) before managing to run the last 1/2 k.
Not sure what happened really - not cold today, so wasn't the cold air. Maybe it was the traffic fumes from the main road? Maybe I'm coming down with something? Maybe I'm still not over the various coughs/colds I've had? (although I managed 30 mins without any problem on Thursday) But the first time I have really had to use my inhaler while out since about week 2....
