Do you want to do a team race together in the finger lakes?
In 2018, we ran a 77mi relay race around Seneca Lake, biking when we weren't running, and spent the rest of the weekend at a massive beach house with a hot tub.
The race website is here:
http://www.seneca7.com/. I'm trying to gauge interest now so that we can register team(s) at the end of October. The race takes place on April 26th.
Each runner runs about 11 miles (77 / 7 = 11) split into three legs. Some of the legs are a bit hilly!
Biking is a team decision. It makes it much easier to register - you get an extra day, when the race typically fills up in 3 minutes, otherwise. It also makes it into less of a mini-Ragnar and more of a holy-crap-we've-been-moving-for-ten-plus-hours accomplishment. Bike teams can receive no vehicular aid. It is extra challenging.
Van teams are probably fun, too! You have to rent or otherwise have a vehicle capable of carrying 6 stinky friends all day, and you each just run your 3 ~3mi legs in turn. We didn't do this, so I can't speak for it.
