Not a fun climb, doesn't feel like a climb but you don't progress because it's false flat + cobblestones.

Geen leuke klim, voelt niet als een klim maar je gaat niet vooruit doordat het vals plat is + kasseien.

I did this one once, now I avoid it. It is an alternation of poorly run concrete track (which is often crowded) and cobblestones. The cobblestones are not spectacularly bad but on the steepest stretch it gets a bit gruelling. The main reason for me to avoid this one is that there are so many nicer alternatives nearby.

Ik heb deze één keer gedaan, nu vermijd ik deze. Het is een afwisseling van slecht lopende betonbaan (die vaak nog druk is) en kasseitjes. De kasseien liggen niet spectaculair slecht maar op het steilste stuk wordt het toch even afzien. De voornaamste reden voor mij om deze te mijden is dat er zoveel mooiere alternatieven zijn in de buurt.

The cobbles are bad, it is at the steepest part 'stumbling' uphill. Fortunately, it is not that long. Otherwise a concrete track that goes up and down a bit

De kasseien liggen goed, het is op het steilste stuk even 'stoempen' naar boven. Gelukkig is het niet zo lang. Voor de rest een betonnen baan die slecht loopt.
