I only know that both of those climbs are in Rouvy:
Gotthard,
Furka. Based on the stats, looks like it would take a big part of the day to do both, roughly 4 hrs if you can average 3 W/kg on the climbs.
I wish that I had the opportunity to ride in Switzerland when I vacationed there a few years ago, but was with extended family the whole time. Next time for sure, though.
Funny cycling-related story I had from my trip. We got on a boat on Lake Geneva thinking it was taking us from Lausanne to Montreaux. The only other people on board were on a cycling tour, fully kitted with their bikes and matching jerseys. I thought it was an odd way to travel since they could just ride over, then I realized we were on the boat to Italy and had to hastily run out and onto the correct boat. The Swiss trains are punctual but thankfully not the lake cruises!
