I don’t monitor my speed all the time but it does provide useful feedback after a run.
A small step-up from the previous model, the 620 seems to lock on the GPS satellites quicker.
It has a couple of other cool features too: recovery and VO2 Max.
The second predicts my race times over a handful of distances based on what it calculates as my overall level of fitness.
And I love that!
