# Wrong course length!

Just completed Serpentine 8. It states 19.3km but to complete it is actually 26.5!!
Why not just put 26.5km!!!

Welcome to the forum.

Because the loop has a lead-in, you have to ride to get to the start.

Yeh I realise that but you still have to ride 26.5km to complete!!! So why not put that is all Iām saying, itās the same with other courses as well !

The main factor in the distance statements is that the route is repeated, without the lead-in, if you continue riding with no input of turns.
For instance, the volcano circuit is stated as:
Length:** 4.1 km (2.5 miles)
Elevation: 17 m (56ā)
Lead-In:** 1.3 km (0.8 miles)
If you ride the circuit 1 time you ride the total of the lead-in plus the circuit however, if you ride the circuit 10 times for the badge you ride the lead-in once and then each following circuit is the stated route length. Thus the need to differentiate between lead-in and route.
Hope this clarifies.

Okay. Iāll bite. What about routes that donāt finish where they start, like āTour of Fire and Iceā? Why canāt that one just be total distance necessary to complete the route, rather than having a 2.8 km lead-in?

Consistency. It makes sense for all the route distances to work the same way, loops or not.

We should be praising Zwift for this!
