I am hoping to sign up for the 1/2 marathon in Nov. I’ve been out of really running for about 4 years due to 2 pregnancies and 2 babies since 2013. Back when I was running I had a Garmin 210, I think. I need something similar. I just want to be able to see my current running pace, pace per mile and distance as I go. I am looking at maybe a Garmin 10 or 15? Is there any new brands or models I should be looking at?
