Hi Kylie thanks for the question. As we have a tail end rider and go out of our way as a rule to welcome new riders I think you should be fine. The speed will increase with time in the saddle. I remember when we GW struggled to average 20 km/h on our rides so I think all will be happy to help out. The main issue may be the distance, eat a good breakfast and bring food to eat at the rest breaks. I will send you a friend request if you have any other questions please ask.
