Don't know if this has been done before... but it might be interesting to collect stories of when you've been prevented from achieving a PB by some unfortunate event, or maybe seeing someone/something that needed your help.
Or maybe you ruthlessly refused to interrupt your PB attempt when people needed help... What is that guilty secret?
I ask this because I trod a fine line recently, when walkers asked me for help. I was alone on a relatively remote riverside trail,11 miles into an attempt to beat the 2 hour mark for half-marathon distance training run. I slowed down to answer their question "is there a bridge near here where we can cross?" But I answered on the move, and carried on. Only later did I think that the perplexed looks on their faces were probably telling me that they had a follow up question - but I hadn't hung around. Maybe I was a bit rude, but at the time I thought I'd helped them (for the record, I got a PB of 1:59:53 !)
That's a pretty mundane story. Come on... there must be some good ones out there
