Matt, Tracey and I got together to volunteer at Markeaton junior parkrun on a frosty day. It was good to welcome Matt, who was doing his first GoodGym group run. Thank you for joining us, Matt! It looked very quiet indeed as we walked to the start, then Tracey did some detective work and we walked on to Course B. This is all on grass and runnable when frozen. It was hard to put the funnel into the solidly frozen ground, but we got there, and then we joined in the warm up: very much welcome! Matt and I tail walked, thus keeping warm, while poor Tracey was standing still as a marshal. After the event, we ran together to Matt's car: he had to make a quick getaway. Tracey and I then ran intervals on the parkrun course.
