Hey everyone, I will be running my first full marathon in around 2 months. I am a heavy runner around 170lbs. I am targeting around 4.5hrs for it. Recently got a new ON Cloudmonster 3 Hyper and loving them. By the end of the training block I will have around 450kms on them. Should I use them for the Marathon? Or should I get something else for the race?
