I thought it was a reasonable pace. It's the pace of a CTC B ride. Of which I have done many. It's two hours for a 25 mile ride including a short break. Not a hard and fast rule. Just an indication. Its hard to organise these this to suit all. You can let the racing snake buzz off into the distance. But if somebody is very slow it will frustrate others. Hence the short local circular run to let you make a decision.
