Speed Hike 25km/600m Elevation

Hi,
I plan this 25km long with 600m elevation hike for Saturday, 22 August.
After the hike, we will go to a restaurant in Konz at 3 pm.

Arriving time:10:20
Departure time: 10:30.

Please be sure you can maintain speed, and you hike regularly avrage 5,5-6 km/h. Charge your phone in case your pace is slower; you need to find the way back.

Take enough water, some food - "sugar", and a rain jacket.

Hope to see you,
Krisztina
