Gravel and Tar Classic launched 2016 in Manawatū-Whanganui, New Zealand, gaining UCI 1.2 Oceania Tour status in 2018. It is an elite/international-license-only UCI road race with gravel sectors (the organizer's own site calls it 'the first serious gravel race in Australasia,' but it is UCI-registered as a road race, not a gravel event). The 2025 edition was cancelled due to low entries. The public-facing amateur companion ride has been rebranded 'Slicks and Stones Gravel Assault,' relaunching at a new venue (Apiti village) in April 2026. Founded in 2016 (UCI 1.2 status since 2018). By Steve Stannard / Greasy Chain Charitable Trust.
Reputation: New Zealand's toughest one-day UCI road race with gravel sectors — elite/UCI-license field only. Amateur entry point has been restructured and renamed; current amateur participant numbers not yet published.
