I'm going to have access to transportation and need to go at least 20 miles away from here. There's a 3 mile loop w/only about 250ft elevation gain I'm thinking of tomorrow.

I'd normally be "yeah, let's do it," but it's not well traveled and,
I walk like 5 miles around the city almost every day no prob, just that's usually never more than 150ft elevation gain, and if I get ill there's way more likely going to be someone to take me captive or call 911. I bet I can physically do it no prob, but I don't want to post a trip report tomorrow and get bytched at because I wasn't enjoying a beautiful view of a huge lake, I was "purging."
