If the race was timed with a passive chip on the back of the bib, it does not need to be returned. Multisport events are also scored with an eco-friendly reusable multi-sport timing ankle bracelet. If you did not turn it in at the finish line or packet pick-up, please return it to us within 5 days to avoid having to pay a replacement fee. The replacement fee for our new race|result battery powered Pro Chips is $65 each. Multi-sport tags should be placed in a padded envelope to keep the tag from being damaged. Make sure you affix adequate postage on the envelope (it requires more than a single first class mail stamp!). Any envelope with a greater than 1/4 inch thickness requires additional postage. Please include your name and bib number in the envelope and return to: Sommer Sports, 1271 Commons Court, Clermont, FL 34711
