Moved to Worcester this past year and a runner. West side, tatnuck, burncoat solid options....downtown has a lot more to offer in terms of within walking distance. I'd recommend staying in Worcester city as it becomes extremely suburban/rural outside city limits. I run basically the entire city footprint and outside of city limits for trail running.......it's alllllllll hills....at least I'm in better shape for races. Within city limits you basically have access to anything within a 10 minute drive.
