You can make the ride with no real problem. I have taken the MTV bikepath from Mt Vernon down the hill to Riverside Park. I don't know how the trail is from there as I cut across the parkway and take a residential street that runs along the parkway. This allows me to keep my speed up since the bike path has too many turns or people in my way. I connect back with the bike path before the Belle View Marina and follow it into Old Town. I have taken the bikepath from Old Town to Bethesda last week with no problems. I would assume you should have no problem the whole way. I know it was a mess a few weeks ago but I believe it's cleared enough to ride from Mt Vernon all the way to where your going. The few bridges I have gone over were fine.
