I don't know about the rest of you newbie runners but trying to keep an eye on time for intervals was driving me crazy!!
I found this great little gadget called the gymboss. Gymboss.com although I bought mine off Amazon.
You can set both times for running and walking and it vibrates to warn you so no more constantly looking at your wrist.
I totally love mine. I also like not knowing how many seconds are left before I have to run again
.
Just a little FYI. Just completed W2D2 and it feels great! Good luck to everyone.
