Check out COROS for super accurate data. I use the COROS Pace 3 and arm HR monitor: https://noxl.ink/h-nIrw In this video I show a full day of training for the Mesa Half Marathon. That includes a hard threshold workout, strength training, a cross training double on the arc trainer, a walk with Georgie, lots of good food, and some sarcasm of course. I am so excited to take on this new distance. I hope you enjoy following along! #AllieOstrander #HalfMarathonTraining Our new PODCAST! https://open.spotify.com/show/7bHea98O7f25FiTVSP5AEn?si=708303c1dc1d44a7 MY COFFEE!! https://thetworoosters.square.site/?shipping=true&item=29 Try LMNT electrolytes: https://www.drinkLMNT.com/allie for a free sample pack.
