The starting height is 10m at the entrance of Ooidonk Castle in Bachte Maria Leerne.
The finish is 16m away in the Lauwestraat in Wevelgem.
A bridge is taken after 7.5 km over the canal from Schipdonk to Deinze to reach the left bank of the Leie. Another short slope is taken after 25km at Ooigem where the canal is crossed to Roeselare.

Also perfectly cycling of course. And don't forget that in Wevelgem you can take the train back...
