parkrun Stopwatch Bingo Challenge
I found this using the Running Challenges Chrome extension. Its a challenge to get a parkrun finish time for each second of a stopwatch. Given that its practically impossible to plan a finish to the second, its really a matter of luck over a period of many runs. I completed mine with :59 at Lyme Park in the Peak District in September 2017. Well, kind of ..... there was something wrong with their timing that day and I (and I assume others) was recorded at 59:59 rather than 29:39 as my Garmin has it. Its going to take a while to get a real :59 so I'm claiming it for now.
