AN enduring open water swimming challenge is set to return to Glasgow with more than 1000 hardy souls taking part.

Red Bull Neptune Steps challenge will take place at The Maryhill Locks in March next year with twice as many participants as this year’s event.

The 2020 event will be the biggest ever held in Glasgow and will now be expanded to a second day of swimming in the icy-cold waters of the Forth and Clyde Canal.

The course features seven lock gates, all with their own obstacles to negotiate.

While the challenge has typically been dominated by endurance athletes and experienced open-water swimmers, Red Bull Neptune Steps 2020 will include a more accessible pairs relay competition.

Erin Jeffery, triathlete and winner of the 2019 women’s race, said: “It’s a tough event that tests a range of skills, but I was able to push myself harder than I thought thanks to the cheering crowd and brilliant atmosphere of the event.

“It’s a race, so of course the competitive element is important, but results aside, it’s a huge achievement to finish.”

Athletes can register to take part when tickets are released on November 14.
