A quick check on Google might turn up useful information. Good luck!

This would be a good start to find out about others who have done this swim. Also Penny Deans Open Water Swimming is a good reference. Since you’ve done 15K swims before you should be comfortable with feedings so make sure your partner gets comfortable as well. In a 45 mile someone is going to be doing some night time swimming. This freaks out some swimmers, so make sure you get in a few 2 to 4 hour night swims in your training. Will this be with or without wetsuits? For your newbie friend, work on open water navigation. While less important in escorted swims, learning to work with an escort craft does take a bit of practice. There are lots of other threads on this forum that talk about this very subject, so check these out. Also, the Masters Long Distance Committee Chair (Marcia Cleveland) lives in the Chicago area, she is a great resource for open water and Marathon swimming.<div style="clear:both;"></div>
