Pinnacle to Myrtle Forest | 12.0km | 320m ↑ | 1,030m ↓ |  Map

Off The Pinnacle and straight down Pinnacle Road for a couple of kilometres before heading off down Big Bend Fire Trail and over the back of the mountain, with views of the Collins Peak and the side of Sleeping Beauty. Turn on to the technical single track over Mt Connection through alpine marsh, snow gums, and the famous Tassie waratah. A short rock slab slide and flowing tight single trail brings you out on to East West Fire Trail and the climb up on to the shoulder of Collins Bonnet, before dropping down on the single track through old growth eucalypts and rainforest. Then it's down through a couple of creek crossings, and more waterfalls and ferns to the Myrtle Forest Aid Station.

If you like the alpine vegetation, epic views, a bit of exposure, and enjoy technical single track and a some descending - then this leg is for you.

Pinnacle to Tolosa | 14.3km | 105m ↑ | 1,235m ↓ |  Map

So you’ve just climbed the entire mountain from town, now descend the entire mountain via a traversing route across the shoulders of a couple of subsidiary mountains down into Tolosa. This leg is almost all on reasonably well-maintained fire trail and is a fast descent – generally gentle and undulating with a couple of steeper pinches, then a steep and loose final descent into Tolosa, and cheeky little uphill to get to the aid station. There are four dominant vegetation type sections of this leg: Alpine snow gums give way to tall wet then dry eucalypt forest, and finally sheoak scrub down in the valley.

Climb Knights to rejoin the Ultra 66km Leg 2 course. Knights Creek Fire Trail follows a prominent sharpish ridgeline from Tolosa all the way back up to the mountain’s shoulders – it’s a locals’ mountain vert favourite, and you climb straight up it! Then on to the Mt Connection track re connecting with the Ultra 66km course.

Myrtle Forest to Mountain River | 12.4km | 570m ↑ | 930m ↓ |  Map

After a kilometre of flat to warm up, climb straight back up on single track through the rainforest, massive old growth eucalypts and waterfalls. Then it's back up to the snow gums and alpine scrub to climb Collins Fire Trail and the undulating East West Fire Trail, curving across Sleeping Beauty’s neck. Then the epic views down the Huon Valley and out to Bruny Island emerge, and you drop down the biggest descent of the run on Mountain River Trail – an old and rocky fire trail. Down, down, down it goes on the southern side of Kunanyi; back through similar vegetation types except there aren't any old growth trees on this side – you may even see the stumps of the old giants and an old saw pit site of two. You’ll know your quads a little better after the 900 metre (straight down) descent, which pops you out on the gravel Mountain River road for a few kilometres, through the farming valley of Mountain River and to the aid station, located on a generous farmer's property.

This leg is for the downhill frothers! The diversity of landscapes, views, mountain and valley mean that those who run this leg will connect deeper with the mountain, its history and culture. It's a must-do leg for everyone once they get the downhill quads sorted!

 Cathedral to Fern Tree | 11.2km | 415m ↑ | 250m ↓ |  Map

Heading back up the Cathedral Rock track for a couple of kilometres, high-fiving the crew on the way down, you cross the NW Bay river bed and head up a short(ish…) steep climb. It's up a fire trail, dubbed Siphon’s ugly cousin, and it to connects to the Pipeline Track. Stride out the next 7km on this comparatively flat and smooth track (just watch the occasional root!) to Fern Tree Bower, then it's uphill through a ferny gully with an old water supply race (that's a water channel) to Silver Falls. Continue along the Silver Falls trail to the classic Fern Glade track down to Fern Tree and the aid station.

 Fern Tree to Runhub | 7.3km | 205m ↑ | 530m ↓ |  Map

This one is for those who like all the glory that comes with crossing the finish line! And it’s also perfect for history buff runners. Heading down the Pipeline Track past a couple of century old stone arches supporting the water pipeline, you’ll turn in at Halls saddle. Past an old quarry, and zigzagging up (check out the view of the organ pipes!), then down a short single track through silver peppermint forest around Chimney Pot hill. Cross the road and back down on to the pipeline track to the old stairs down Gentle Annie Falls. You’re now in Waterworks Reserve and will take the single track around the dam that supplies drinking water to Hobart. Zig then zag gently up the last hill to Huon Rd, then bomb down rough steep tracks to Cascade paddocks. Near the home straight, if you’re in the relay, your team mates and or/family members can meet you to cross the finish line together as a team. Enjoy the recovery area with hearty food and drinks available for purchase including some classic Tasmanian beverages.
