Are Park Runs Destructive ?

[OB1]

Did Huddersfield on Saturday morning, my 15th different parkrun event. Good little course, 2 laps with a wee bit at the start to stretch the field, light undulations and turns and some criss-crossy under/over bridges and tunnels sections that I haven't encountered anywhere else yet. Good standard too, 19.29 got me 22nd out of 300+, that would be top 5 in some I've run. I'd put it in my top 5 parkrun courses. Going to knock Burnley, Congleton and Delamere off next.

7D, 15 courses in 29 outings, with 10 venues run sub-20, now that's some consistent and dare I say it, destructive, touring! Well done.
Interesting to see that your Oldham time (dry weather?) is faster than your Platts time (wet Xmas/New Year weather?).
Mine (both dry times) are the reverse, so logic says that you have a sub-19 in the tank on the Flat at Platt in the dry one spring day.
