Welcome! The club has a regular series of group gravel rides that have typically run on Wednesday evenings and Saturday mornings and include different paces. The intermediate group, who is usually led by the friendly and capable @jdaley54, is a “no-drop” group.These groups can get spread out a bit, but regroup at junctions to keep everyone together.
There are also group road rides. In years past, there’s been a learn to group ride (which I found to be really good when I joined the club) if you aren’t used to riding in close groups. Like the gravel rides, the road rides have groups by pace, with the recreational and intermediate groups being no-drop. These groups tend to mostly stay in tighter groups to take advantage of the draft.
That’s just off the top of my head, but there’s some official docs in the FAQ section that are helpful if you haven’t already read them: Docs - Waterloo Cycling Club Forum.
Peter, welcome to the club. Our scheduled gravel rides will work really well to help you achieve your goal. Saturdays we generally ride between 60 and 70 km and often find ourselves at Anna Maes for a fritter! The Wednesday rides will start with shorter distances and ramp up to 50 - 60 km as the days get longer. We usually get going in March and we typically go as late as possible(ie December) in the fall. Keep an eye on the rides section of the forum. That is where we post the organized rides. Looking forward to having you join us.
