A series of temporary local road closures and traffic regulations are in place in Keswick today for the Lakesman triathlon.
Competitors will swim in Derwentwater before riding 112 miles and running a marathon along local routes.
The road closures have come into effect overnight and will last until after the event, which is based at the Lakeside car park.
They involve vehicles being banned from stretches of Lake Road and off High Hill from its junction with the A66.
An alternative route for vehicles will be available for the latter via the A66 and Crosthwaite Road.
A stretch of Church Lane will also be closed from its junction with High Hill, with no alternative route for vehicles.
The road closures or no waiting restrictions being brought in by Cumbria County Council will also impact Cockermouth, which the cyclists will pass through, up to Lamplugh roundabout.
