Flew into Geneva (landed early morning). Took train from Airport to Chamonix-Mont-Blanc train station (couldn’t book French tickets on the SBB app so I had to go to the ticket booth in person when it opened). Walked from the train station to the Gare Chamonix Train du Montenvers (stopped along the way to get food/water). Rode the tram up to the Refuge du Montenvers. Booked my room in person (almost nobody staying there in October, it’s middle of shoulder season). At this point, it was early afternoon, so I changed into running gear, left my bags with the front desk, got out on the trails.
Did an out-and-back along the apron under the mountains. Weather was rainy in the morning but transitioned to partly cloudy in the afternoon. Steep section at the beginning, then lots of super nice rolling trails. Turn-around point was Plan de l’Aiguille. Views of the valley the whole way. No scrambling at any point. Strava
On my way back to New York, I stopped through Geneva and ran along Lac Leman. The waterfront has a pretty nice, uninterrupted path with gardens along the way. Strava
