Two Lauras from Hawke's Bay - Nagel and Langley - are setting the pace as the best in their disciplines at New Zealand level.
Nagel reinforced her status as the country's 10km queen after claiming the New Zealand Road Championship crown in Masterton on Saturday.
The 24-year-old from Napier, winner of the national 10km crosscountry titles four weeks earlier, stamped her supremacy when she extended her lead on Lydia O'Donnell and Sally Gibbs on each lap to stop the clock at 35m 14s.
O'Donnell finished runner-up in 35:46 while Katie Kemp stormed home for third place in 36:08.
