I did the Bedford Glow in the Park last year and absolutely hated it. To the extent that I didn't bother to use the free place they offered me for another event as a thank you for handing out loads of flyers for them.
It was too soon after I tore my calf and I was in agony for most of it which I don't think helped but I don't know of anyone else going back either.
It's a proper trail run around a lake and is 2 laps for the 10k. Unlike The Spooky Sprint (which I would do again) they started when it was already pitch black so you didn't have the opportunity to scope out the course in the twilight on the first lap and were just running blind for the whole thing which was hard going when the course was in places very muddy and up/down hills too. Lights were apparently placed 200m apart to guide you round but there were a couple of places where the course doubled back on itself and was less than 200m away from the return so it got really confusing as to which direction to run. Timing was done with 'dobbers' rather than chips so you had to queue at times to cross the finish line too which affected times. There were no bib numbers either, we just had them written on our hands.
The medal was a bit rubbish too imo.
Last year's was the first event so hopefully they've made some improvements for this time and there must be a few people going back. I won't do it again though.
