The Chilly Duathlon is by far the Southwest's biggest duathlon, whilst the Manic Summer Duathlon Series is one of the country's longest running multisport race series.
They're both held at the same venue and in 2015 they are coming together, to form the Southwest Duathlon Series.
There will be cash prizes up for grabs for the series winners - to qualify for these you must compete in both Chilly Duathlons and a minimum of three Midweek Duathlons.
