COURSE DESCRIPTION

UPDATED FOR 2024.

Step 1: Sign up in a moment of madness/clarity
Step 2: Enjoy the hospitality of Settlers Arms Inn on Friday night.
Step 3: Wake up as the MC screams ‘GOOD MORNING ST ALBANS!!!’ and question your choices.

100km riders leave St Albans heading north, the first 12km is nice, flat and easy, the perfect opportunity to find your pace and your place in the crowd. At the 12km mark that all changes as you turn away from the valley floor and head for the hills. The climb up Browns Trail starts steep, so knuckle down and grind your way up (and really start wondering why you signed up for this). There is a false flat before it kicks up again, as with all great climbs, it is steepest at the top. The Aid Station at the top will be a welcome sight. Ignore the signs pointing along the 48km course, you are only just getting started.

After stocking up on supplies and rolling down what is known as Sullivans Arm you turn right, onto a long untamed and remote stretch of the Old Great North Rd and head South. Welcome to the Convict 100! After what can seem a lifetime, you know some ‘relief’ is waiting as you pop back out at a five-way junction. From here it is downhill, past the remnants of Claire’s Bridge, historic Ten Mile Hollow and the Wat Buddha Dhamma retreat. The fire trail is wide and smooth, it’s a good thing too as you now have a climb up to the second Aid Station at the top of the Eight Mile track. You are getting there but plenty of riding still to come.

The Eight Mile track is little used so take care down the hill, especially after you pass the Private Property sign. Once you hit the bottom keep those wheels moving and keep an eye out for any rogue camels (and no we aren’t joking!) At the end of the farm road where it joins Settlers Rd the real decision awaits, turn right and it’s a flat 8kms to home, turn left and you have 40kms to go. This is where all those hours of training kick in.

A short flat sprint along the road and then turning off and climbing again, up Shepherds Gully, joining The Old North Road and the Convict Trail. Winding single track, technical (natural) rock gardens, scenic views across Dharug National Park and cobble stones laid out by a cattle thief many moons ago. The enjoyment of the riding and the views will help take the fatigue out of the legs. Suddenly, you are out of the wilderness, back at the top of the Eight Mile for your last visit to an Aid Station. The end is in sight!

The next stretch will be familiar (you rode it earlier in the day) but fatigue will be high so take it easy, use those brakes and before you know it you are back on the flat, this time turning right at Settlers Rd. This is the last few kilometres, time to empty the tank, if you have anything left, along the flat roads to the hard-earned finish line where your medal and an ice-cold drink is waiting!

Your adventure is complete.
