Relax the Saturday afternoon away near the finish at Dolgarrog, where you can chat about the day's paddling over a snack while waiting for prize giving in the central building of Adventure Parc. The snack is provided by the organisers, as part of the entry fee for participants, and for a small price to non-participants.
There are lots of things in the area you can do on the Sunday, so why not come for a weekend in Snowdonia? You could try dry-slope skiing, climbing, walking, mountain biking, pony trekking, kiting, stand up paddleboarding, ten pin bowling, fishing, sea kayaking or countless other activities.
There are B+Bs, bunkhouses, campsites etc. listed on the Accommodation page
