The race series is held in the Spring each year in the 8 weeks leading up to Easter. They are held on Sundays at fortnightly intervals starting 8 weeks from Easter and the races are progressively longer in distance.
It is common to use the Waterside Series as a warmup event for the longer, 125 mile Devizes to Westminster International Canoe Marathon, however despite the reputation as a warm-up event, it is considered a gruelling challenge in its own right.
- Waterside A - 13.5 miles (21 portages) from Great Bedwyn to Newbury
- Waterside B - 17.5 miles (19 portages) from Newbury to Aldermaston and back
- Waterside C - 23 miles (35 portages) from Pewsey Wharf to Newbury
- Waterside D - 35 miles (35 portages) from Devizes to Newbury
The races take place as a time trial format, whereby competitors choose their own start time within the start window and must finish within the finish window. The opening and closing times of these windows varies from race to race with the longer races have earlier start windows and/or later finishing windows.
Races C and D include Savernake Tunnel, where overtaking is prohibited due to safety reasons.
The Waterside Series attracts a range of entrants from regular marathon paddlers based at clubs around the country to endurance athletes from other sports seeking to use the races for training, the race is also popular with public schools and the military.
