Half marathon training - Week 1 - Speed run

Today was the first workout of my training for the Columbus Distance Classic half marathon, which is April 14th in Columbus, Ohio. I ran it last year and enjoyed it, so I'm returning this year.

The workout today was a speed workout, with a goal of doing 8 repeats of 400m (1/4 mile). So as you can see from the graph, lots of squiggly lines. The workout went well, as I finished my 4 miles in 31:40, for an average pace of 7:52/mi. So my training is off to a good start.
