Hi Frank,
Thank you for your e-mail. Thank you for your participation at the Inaugural Rock 'n' Roll Providence Half Marathon! We do provide the 'SAG wagon' at all of our events. Once participants are collected in the sag wagon, their chips do not continue to read on the correct splits & mats. Therefore, they are considered as a disqualified participant as not having completed the full 13.1 miles. Please let me know if you have any further questions or concerns. Have a great day!
