Scheduled for the 2nd week of the NZ school holidays, incorporating the following;

A carbon-friendly, central Dunedin-based, 2-day, 2018 South Island Orienteering Championships, held on brand new or revised areas, mapped 2016/7 by Bryan Teahan.
Afternoon, Saturday 21st April.  Urban Short Distance - a "long" Sprint event, starting from the top of the Dunedin Botanical Gardens, going through the University of Otago/Otago Polytechnic campuses, finishing down towards Dunedin waterfront.

Sunday 22nd April. 
Middle Distance - a "long" Middle Distance, where competitors are taken by bus to the top of Signal Hill at 393m, then race down through tight/technical/single tracked, open pine or native forested/tussock vegetation, into a multi-level high school complex, and finish at sea level in a stadium.

Move on to Alexandra by the afternoon of Anzac Day, Wednesday 25th April, for the 2018 National Mountain Bike Orienteering Championship series.  This is a premium time of year
in Central Otago for autumn colour, and pleasantly cooler-than-summer temperatures for competing.

Wednesday 25th April.  MTBO Sprint, afternoon, near Alexandra.  Very complex tracks in an old gold mining area.

Thursday 26th April. 
MTBO Long Distance on the Linger and Die, Alexandra.  Completely revised map and courses planned to minimise climb.

Friday 27th April.  MTBO Middle Distance, 20km north of Alexandra.  Fast riding in undulating grassland.

To finish the week off, Highland Events provisionally wish to hold a Rogaine on Saturday 28th April, somewhere in Central Otago.  They usually hold a format of 3, 6 and 12 hour events with an MTB option on the 6 hour.

Flying down?  Book to arrive in Dunedin at the latest on the morning of Saturday 21st April, and go home from either Queenstown or Dunedin airports on Sunday 29th April.
