I'm 30 years old, used to be really into running half-marathons in my early 20s but unfortunately lapsed in running for about 4 years, and am now getting back into it (past 2 weeks been running nearly every day!).
We run and explore the roads and trails of Oakland and Berkeley every week. Road Runs are typically in the 4-6 mile range, Trail Runs are in the 5-8 mile range. You can also sign up for a separate run (and store insider) email list for free at either TRANSPORTS location.
