Both the traditional 16km and a new 22km course are available.
NOSH16
(and first portion of NOSH22)
This is the classic NOSH course. It’s picturesque and challenging but achievable. We offer both a running and a walking class over this distance.


The race starts at Lindfield and winds it way along picturesque water edge trails to Roseville Bridge. After crossing the bridge, the course then takes runners through Killarney Heights and includes trails through Garigal National Park that climb to Forestville before finishing at Seaforth Oval.
The course is primarily off road and the terrain is rough in places so you need to watch where you place your feet. This is a natural bush track, not pavement, so there will be tree branches and roots. Please take care as falls and sprained ankles do happen. Times are considerably slower than on flat or smooth terrain.
Due to an extended closure of part of the Flat Rock Track by National Parks there will be a slight detour to our traditional course. The current course length is a touch over 16km. It is the same route as used since 2016. The current route includes an additional climb to take in beautiful middle harbour vistas from Killarney Heights.
There are only three locations where you will run beside public roads: firstly across pedestrian path on Roseville bridge and down the ramp on the eastern side (which is the exit from the National Park), secondly, on the Killarney Heights detour and, thirdly, a couple of blocks in quiet, suburban Forestville. You must obey the course marshals directions, and keep to the left of all traffic cones.
The course will be marked by streamers and kilometre markers.
NOSH22
This course option was introduced in 2019 and offers a more challenging run.
The first 16 kilometres are the same as for the NOSH16 however when runners almost emerge from the forest in Seaforth, these legends will dive back into the trails for another 6km loop. The loop heads down hill on the historic Timbergetters Track to Bantry Bay before crossing some creeks and climbing through forest and rock back to Forestville. Runners then return to Seaforth Oval for a grand finish.
The additional loop is rough and steep in places and adds a further 130m of climb to the run. It is only suited to runners who have trained up and are prepared for a tough 22 kilometres of trails.


REGISTRATION AND START
Prior to starting the race, all entrants must register and collect their race bibs. Options for registration and bib collection are included on the Event Information page. Race day registration is at Lindfield Soldiers’ Memorial Park, Tryon Road, Lindfield from 8:30am. Upon arrival at the oval, head for the grandstand where you will find some friendly faces to assist you.
The start is on Two Creeks Track, down the hill and to the north of the Grandstand. Allow a 10 minute walk to get to the start which will be marked.
At the start, please queue along the track with fastest runners at the front and walkers at the rear. There is no need to hurry to cross the line as your race time will only start when you cross the line.
WATER STATIONS
There will be two water stations. One at the 6km mark on the eastern side of Roseville bridge and one at 13.5km in Forestville.
NOSH22 runners will also visit the second water station at approximately 19.7km into their course.
Cups and water will be available however runners are encouraged to carry their own reusable drink containers and refreshments.
CUT-OFF TIMES
A sweep will follow the back of the field. Cut-off times will apply based on all runners or walkers reaching Seaforth ahead of a 1:30pm course closure. If you fall behind the sweep, you will not make Seaforth before official timing closes.
