Running (and winning) a proper race abroad is great fun. No one knows who you are, you just turn up out of the blue and smash it.
Going abroad for a parkrun is nuts though.
I once went to the US and won the only parkrun there and set a new course record thus becoming the fastest ever parkrunner in the whole of the US. I'd like to say the trip was specifically to that end but it was just pure coincidence that the armpit of a hole where the first US parkrun was founded was less than a mile from one of our offices. SG, I would have thought a quick parkrun in the morning of an any games would see you tick along nicely. Only issue is if you shower afterwards or go to the match "parkrun fresh".
There used to be a number of "festival of running" events, often over a bank holiday weekend, which included a 5k, 10k and half on consecutive days that would make an ideal thread outing bu they now seem to be 3 or 4 races on the same day and that mucks the whole concept up.
SG, the WAVA tables are infrequently updated and (IMHO) are generally inaccurate in the less populated areas, so less data for older runners and less data for females vs males.
parkrun is pretty much 50.50 male and female but look at any parkrun, so I pick Maidenhead as an example as you recently did this, and look at the top 10 age graded results, For Maidenhead, there are 8 ladies and 2 gents (including our own PeteM in at 9th place) and the 8 ladies are 5 vets, 2 senior and 1 junior, the 2 gents are both vets. Why is there such a bias towards ladies and old ones in particular?
