GreenTech Run
A curated morning run and cool-down for founders and investors, the morning after smart green's GreenTech Capital Forum.
The morning after the GreenTech Capital Forum, we're inviting founders and investors in town to shake off the conference chairs with a relaxed group run through Freiburg. We'll start from Freiburg Mitte and head up into the forest for a route with some of the best views the city has to offer, before finishing in the old town. Expect roughly 6 to 8 km at an easy, conversational pace, no one gets dropped. Afterwards, we'll cool down with some refreshing drinks together, a chance to keep the conversations from the Forum going in a more relaxed setting.
Expect fresh air, good company and a sharper way to start the day after the conference.
