1 in 20

The 1 in 20 is one of the most popular climbing routes in the Dandenong Ranges. This route winds up from The Basin area to the scenic Sassafras, providing a gentle climb and one of the most beautiful places for cyclists to push the limits.

The name comes from the steady gradient which makes up the climb, for every 20 metres you ride you climb 1 metre in height. It is because of this mountainous landscape that this ride offers breathtakingly beautiful views of the surrounding region.

The climb begins at the Basin, so cyclists should look out for the 60km speed sign and find the section of the road that is marked with the word “start” in yellow paint. The climb ends at the 50km speed sign located in Sassafras.

The first few kilometres of the climb are easy with a gentle gradient. There are flat sections with a minimal gradient which are good spots to admire the beautiful surroundings as you cruise on by. Most of the climb sits art around 5% gradient for a steady climb to the top. The last 2.4 kilometres of the walk is gentle with minimal changes in the gradient.

1 in 20 stretches for 6.8 kilometres and has an average gradient of 4-5%. Many cyclists use different apps to record their best times, with the time to complete taking anywhere between fifteen minutes and half an hour, depending on your skill level.

1 in 20 can probably be categorised as a level 4 climb as it has a steady incline, but is not very difficult. However, cyclists should be aware that this road is utilised by motorists and therefore road safety precautions should be adhered to.

There is car parking near the shops in town, however, there are time limits to be aware of. Other parking options are near the Fire Station. There are also toilets at the start and finish lines of the 1 in 20.
