I located two running events in March that I'll be using strictly for speed workouts. I won't be leaving it all on the course at either of these events but rather give a 85% or so effort. When one trains solo, it can be hard to find the motivation to dig deep for a speed type workout. Always easier to pace yourself when running with others.
Mar 12 (signed up) - Chase a Leprechaun 5K; Becker, MN
Becker is a small hamlet west of the Twin Cities more famous for its huge furniture store. Close enough that I can sleep in a bit as it is a 10:30 AM start.
Mar 19 (signed up) - Get Lucky 7K, MPLS - 7K (4.52mi)
I like the distance. Especially with my first international event, a 10K in London, two weeks later. A 5K-7K tuneup should be just about perfect. And a cool finishers medal.
