I wonder if anyone could tell me or point me in the right direction for where I can find out if there is any sort of record for doing the DW in a 4 leg relay? I have read through previous posts and couldn't see anything although I assume a relay would have to beat an individual (18 hours?).

The reason for asking is that we intend to do it for Cancer Research and want to put some context to the challenge (although don't anticipate getting close to any record). We are a mixed ability team so can't take on the whole walk (although some of us will walk back afterwards), but intend to run / walk as appropriate and hopefully make it an enjoyable experience for all. Any help would be appreciated.
