2 weeks ago, at my first parkrun after our 7 week long "holiday", I discovered that I had lost 5 minutes of my previous PB. I have been looking everywhere for them since then - over the last 2 weeks I have run 40klm looking for them!! They DID appear to have gone forever!!
But - Anyway - I found 4 of them today -- I guess the last one will show up somewhere further down the track??
That young fella behind me was helping me to find them!!
