Whites Bay track plus Mt Robertson. Is this climb even possible?

This is part of my 2026 Caravan adventure around the top of the south Island of NZ. We are staying in Whites Bay near Blenheim and todays ride is the Whites Bay loop. this is a Black technical trail. We also decide to climb Mt Robinson that comes off the Whites Bay Mountain bike loop track. This was one of the steepest climbs I had ever attempted.
