Wanganui's Van Dalen twins will be in the mixed New Zealand team aiming for a strong performance at the Chiba Ekiden Relay in Japan today.
The squad of three men and three women will run over six legs of varying distance to complete the full marathon distance of 42.195km.
The runners include London 1500m Olympians Lucy van Dalen and Nick Willis, 2013 world championships 5000m finalist Zane Robertson and former world junior cross-country rep Nicki McFadzien.
They will be supported by 2013 double New Zealand champion Malcolm Hicks, replacing the injured Jake Robertson, and Van Dalen's twin sister, Holly.
Ekiden which means long-distance relay running racing is popular in Japan and this notable annual event attracts quality international teams.
