I live in Petworth and work in Van Ness and I bike to work every day and I can’t recommend it enough. I tried metro/buses when I first moved to Petworth but it was really frustrating. It takes me 15-20 minutes by bike as opposed to an hour by public transport. I go up Tilden everyday but for Glover Park you may want to do Porter. If you map it right, a good amount of your journey can be on trails and residential streets, not commuting roads. I take Upshur St to Mathewson Dr to Blagden, I take a right onto Beach and an immediate left onto Broad Branch and into the parking lot. You can pick up the trail there, take it to Porter (If you’re going to the northern part of GP) or continue on the trail to Woodley Park and exit the trail near the Omni Shoreham. You can weave through the residential neighborhoods there to get to your office. Good luck!
