Hey, so I graduated college last spring where I ran anything from 1500-5k. I'm signed up to do my first marathon in mid-november, but I seriously have no shoes for running that distance. I have 3 heavier trainers (nike pegs, brooks glycerine, and hoka cliftons) and an assortment of featherlight flats and spikes (mostly nike or nb) but nothing that I'd want to run 26.2 in. I'd really like to get them soon so I can break them in on a couple tempos or quicker runs before the race. Also, I'm a grad student, so I'm literally poorer than broke, so price is definitely a factor as well. What shoes would you recommend for racing the marathon distance? Thanks!
