As hosts of ManTri and Stockport Triathlon club aquathlons we thought we'd throw out a challenge to all of our swimmers and triathletes.
Race distance is single or double laps (of both the 450m course and 2.5km run course).
The events will have prizes for first, second and third in both senior and junior categories
