So in Keller, North Richland Hills, Hurst, Colleyville, Grapevine, Southlake and Fort Worth there's a pretty good network of trails. These trails are typically wide sidewalks, suitable for walking, running or cycling. While I'm fond of the Keller trails, they lack (peaceful) connectivity to the larger system of trails in Tarrant Co.
I say peaceful, because while Rufe Snow Blvd has a wide sidewalk that can get you to the John Barfield Trail, it's not the most pleasant of of routes (I take Cat Mountain to North Tarrant Pky to get off Rufe Snow). That being said, once you get on the trail (you can pick it up near Rufe Snow and North Tarrant Pky (or near Keller-Smithfied Rd and North Tarrant Pky if you use the Cat Mtn bypass) it is quite peaceful. On the Barnfield Trail you can walk or ride, in relative peace, (almost) all the way to Grapevine (via the Cottonbelt) if you choose. On this day, I did.
I started my walk on the John Barfield Trail, just south of North Tarrant Pky near Keller-Smithfield Rd. Very peaceful place to walk. A little lacking on facilities (water/restrooms), but those can be found further along the trail (Pleasant Run Soccer Complex in Colleyville) or at businesses near the trail. Do bring water though, as it's easier than detouring off the trail.
The trail winds through neighborhoods, eventually ending up at the Cotton Belt trail (near Precinct Line Rd). From here, you can get all the way to Grapevine, but the trail peters out at Highway 26 (Coleyville Blvd).
If there's a good trail into Grapevine (from here), I have yet to discover it.

Bottom line: Once on the trail, it's a wonderful escape. read more
