Robin Austin Judkins is a New Zealand sports administrator. He created the Alpine Ironman and the Coast to Coast, races that are often credited for being the origin of adventure racing. He has published an autobiography, Mad Dogs: Life on the Edge.

The Coast to Coast is a non-standard multisport competition held annually in New Zealand. It is run from the west coast to the east coast of the South Island, and features running, cycling and kayaking elements over a total of 243 kilometres (151 mi). It starts in Kumara Beach and traditionally finished in the Christchurch suburb of Sumner, but since 2015 finishes in New Brighton. The event was created in 1983 by Christchurch personality Robin Judkins, who sold the rights to Queenstown-based tourism company Trojan Holdings in 2013. Richard Ussher took over from Judkins as race director in 2015. In 2019, Glen Currie was contracted to continue on from Richard Ussher in the role of race director.
