At a 10k in the west of Scotland. Late thirties/early 40’s guy, precisely trimmed greying goatee (check), and that whiny, arrogant nasal sounding voice that anyone from those parts will recognise. Totally self obsessed/loving, spouting off to anyone who could hear him about his running, his times, his shoes, his shorts, how he ‘wasn’t sure if his body could handle 2 10ks in a month but he was going to try’. People were purposivrly giving him a wide berth in the hour before the race. Excessive stretching especially knees so he could stand and rotate his head, short jogs with his head swivelling round to see who was watching him (no-one) and all the time the non stop, overly loud running commentary.
I guess he finished in around 46 minutes or somewhere, he wasn’t moving far from the finish line as the last I saw him he was trying to engage other people on a monologue about his running performance.
You really have to have encountered too many of this self obsessed chip on the shoulder type to get the full nuance of how irritating they are.
