World Records for Mass Swim Relays

Information about other results, new records and corrections are always welcome (just e-mail to info@recordholders.org)

The Rules

1. The relays are open for men and women from all age classes. We will also register records for relays swum by females only.
   
2. The records in this list are for feestyle relays. However, we will also register separate records for other swimming styles.
   
3. Attempts can take place in either  25 m or 50 m pools. For the 24 hrs record pools of 25 yards or 50 yards are allowed as well.
4. No swimmer is allowed to swim more than once. In a 1000x100 m relay, for example, actually 1000 different persons must swim.
5. It is not allowed to change the lane during the event.
   
6. The attempt starts with an audible signal, and the clocks stop when the last swimmer touches the wall. Two clocks must run all the time. It is not allowed just to add the individual times achieved for all swimmers in order to compute the final result.
   
7. As usual, a swimmer must not start before the swimmer he or she is taking over from has touched the wall.
   
8. If for some reason a swimmer fails to complete the distance, another swimmer can substitute him or her and swim the complete (not just the remaining!) distancce. The clock remains running. Neiher the swimmer who failed to complete the distance nor the swimmer who started as a substitute is allowed to swim more than once in the relay (see rule 4).
