3 days ago I ran my very first race and it was quite the experience. I was quick out of the blocks, maybe in the first 10 racers, and was doing well until about 10 minutes in, when my asthma unexpectedly kicked in. Cue wheezing, coughing; the works. Naturally I had to slow down, catch my breath, and let the other racers pass me! But once I sped up again, my breathing slowly got better (effects of a long acting beta agonist) and I was able to run to the finish line.
I wasn't entertaining any illusion of actually finishing in the top few racers, so my pre-run goals were to a) finish the run, and b) smash my personal best. Both were achieved; I ran a sub-30 minute 5K for the first time, despite slowing down mid-run.
Really ecstatic, and now I'm looking forward to improving my speed, and stamina over the next few weeks.
