I did a 10k recovery run yesterday with 4x30-20sec strides.
Looking at my top speed on the strides I went fast, top speed 2:33. New PR since I started doing this a few weeks back.

Good job! If you wear your COROS arm band to capture your HR then GPS data and cadence from your watch are most likely quite accurate - unless you run close to Russain border or in deep valleys!
