Orienteering race 17:47 [3] 1.9 km (9:22 / km)
shoes: X-Talon 190
WA Sprint Champs at Willetton SHS. Had to slow right down after 2 when I found it difficult to breathe. This got worse and I had to walk for a while after 4. Jogged through 5 to 10, then was able to run again, including fairly good speed from 11 to the finish. Left 2 in the wrong direction (probably due to the breathing problem, but corrected quickly. Possible route choice loss from 8-9, but I don't think there was much in it. Winner beat me by 3 mins, waiting for splits to see if there was anything more than the slowing down. According to my readout I won the first two splits and the second last, so seems that without the slowing I would have been close.
Using the Tomtom for the first time on a run, I set it to gym as the symbol is pretty similar to the one for run, and didn't get a trace as a result.
Will visit doc tomorrow, possible reason is EIB (exercise induced asthma), have had the same thing happen once or twice on the bike recently, doesn't last long and disappears after a few minutes. Hope it's not something more serious.
