MTB 32:29  9.14 km (3:33 / km) +82m 3:24 / km
Out at Killingworth at the end of the work day and just happened to have a bike in the car so stopped for a ride around Barnsley tracks. Tried to follow the "yellow" loop. Only a couple of missed turns.
MTB 39:57  10.36 km (3:51 / km) +128m 3:38 / km
Second lap exploring different tracks. Seems to be a lot of new tracks being marked out and made by someone or some group.
