You will submit your list of race results and bonus miles, all at once, including the place you finished by October 31st 2021 in order to receive your Iron Runner Hoodie. Please do not email us after each race, wait until you have completed your 50 miles and then send us 1 email for verification.  If you will be using any races in November to complete your miles you may submit and note what races you will run to complete your 50 miles to still receive your hoody.
