Worthing parkrun for me today: 21:42. Pretty ordinary but happy with this as I ran down to the start (3 miles or so) and - such was the quality of the field - managed to beat all the 50+ 'youngsters' (a relative term).
On Cardiff I did a 10K there many years ago (we finished in the nearly-constructed Millennium stadium) and got the impression that it is a hotbed of running......and drinking too. Also saw Sussex win the Sunday League at Sophia Gardens back in the day (happy memories).
Good Saturday workout for you. I did the Cardiff 10k around 16/17 years before the stadium. Nice run through the park and castle. Cardiff is planning an April Marathon. They nearly set it for 2017 but had too many road closures to organise and not enough time.. I would like to do the inaugural run in 2018.
