So, i'm not a marathoner but i think i could run pretty quick and i noticed that the philadelphia marathon offers $3500 to first place and $2000 for second. 2 questions. 1- Is $3500 alot of money for a marathon that posted a winning time of 2:21 last year? and 2, is it worth $3500 to run a marathon if I've never raced competitively over a 10K?
