Separate Transitions...IM70.3 NC

Just finished the swim leg of an IM branded HIM event that was point to point. They had huge white bags at T1 and gave each athlete gear bags. You put your belongings from T1 into a bag then put that bag into the huge Ironman white bag and they shuttled all your stuff back to a commons area somewhere. I was just the swim relay so I simply laid all my stuff on the beach then went and put it  back on when I was finished so I'm not sure where the pick up for full distance athletes was but IM does plan for this. 

As far as your wife finding her way to T1 - sounds like she will have to walk. SWIM:The only way to access the swim start is by  walking the two miles from Transition 1. We recommend spectators wait near the transition area to see their athletes. THERE ARE NO SPECTATORS ALLOWED AT THE SWIM FINISH BECAUSE IT IS PRIVATE PROPERTY. THIS RULE IS STRONGLY ENFORCED BY THE PROPERTY OWNER.

I did B2B in 2014 before it became a branded race.  I also did Vineman where T1 & T2 were 20 miles apart!  

T1 is at the marina.  As I recall, limited parking but manageable as long as you aren't trying to get out of the marina area before all the bikes have cleared.  Look at the map, there's only one road/bridge leading to the marina and it'll be closed for the race!  They offered shuttle buses FOR ATHLETES ONLY from T1 to the swim start.  I *think* they offered buses from Downtown to T1, but we drove in.  

T2 is downtown (3-4 miles away?).  Parking and access are much better.  

The 1.5 mile walk from swim start to T1 may be a problem as you're swimming with the current.  I'm not a fast swimmer, and my B2B split was 48:00 for 2.4 miles due to the current.  By the time she'd see you start the swim, she *might* miss you coming out of the water!  Her best bet might be to hang out next to T1 where she can watch you get your bike and not worry about spotting you coming out of the water.  

If it's just your wife (no kids), a bicycle may be her friend.  She can park the car away from T1 and ride where she can't drive (including from T1 to the swim start).  Downtown, she can park the car and ride from the convention center (T2) down to the run course, around the park to the run turn-around, and from the run course to the finish chute.  (If she's ambitious, she can ride from downtown to T1, but more likely, she'll park on the city side of the channel and just navigate the last half-mile via other means.)  

As I recall, T2 wasn't far from the finish line (6 blocks?) and they brought my transition bag from T1, so the bike and both bags were in T2.  

I'm pretty sure I set up my bike and turned in gear bags the night before the race.  As I recall, I set up the bike and put my T1 bag with it.  I turned in my T2 bag and didn't see it race day until I got into T2.  Picked it all up after the race.  

I've been away a while.  Didn't know that B2B had become branded.

I recall that bags were all delivered essentially to pretty near the finish line.  The year I did it, they were sort of dumped, roughly by number, in different areas.  If that's still the procedure, mark your bags in some unique way (think airline luggage) and you'll have an easier time finding them.
