DD is great, I was amazed at how many people clumped around DD and enjoyed the group ride.
Category D is a very broad category 1-2.5 w/kg so it would be great to have:
DD1 1.5 w/kg
DD2 1.8 w/kg
DD3 2.1 w/kg
DD4 2.4 w/kg
This way you can gradually move to the next higher pace partner and build up your strength and fitness whilst sticking with a bunch in Watopia.
This is a great step forward, and I do hope that the consistency of the pace partner won’t be changed, it gives heavier people a realistic ride partner.
