It'll be hard if you try to go two days in a row. I'm not saying don't do it, but I'd advise against it at least for the first few weeks. Don't be surprised if you're kind of wiped out the first time you go two days in a row, I definitely was. At 34 miles round trip, I'd think that M/W/F is a good target to try to get to by the end of the summer, unless you do better than I did at first.
