Llandudno Half Marathon

Llandudno Half Marathon is a rolling half marathon in Llandudno, UK, held each March. The route follows the Llandudno promenade to the Victorian pier and on towards Rhos on Sea, then returns the same way. It is mostly flat apart from a half-mile climb over the Little Orme. March mornings on the North Wales coast are cool and often breezy, typically 3 to 10°C. With Llandudno Half Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
