The Junior Tour of Wales is an annual cycle race for junior male riders, held around Brynmawr, Blaenau Gwent, Wales. First held in 1981, the race is the final round of the British Cycling Junior Road Series - and as such attracts the best junior racing cyclists from across the UK, as well as elite international junior teams from across Europe and beyond. From 1981 until 1993 the race consisted of three stages held over two days. In 1993 it was expanded to three days and held on the August Bank Holiday for the first time. In 2017 it switched to a four-day format. In recent years the race's final stage has finished on the Tumble: this climb often decides the winner of the race.
