Not only is this the same print...they have been selling these silhouettes for awhile now in the parks. If they just use these for the race weekend and stick a hangtag on them with the race name, that would be supremely lazy of Disney and Dooney & Bourke.
For the Disneyland Half weekend the bag was very race-specific, with the race distances and names on it - not like this one or the Princess one where you wouldn't know it was for a race except that there was a hangtag saying so. As a result (in my opinion) the Disneyland ones didn't sell out and were available in Downtown Disney afterward. I even saw bags from LAST YEAR'S race weekend still for sale in the parks. So from a business perspective...I get that they want a print that will appeal to more people, non-runners included. As a runner, I agree with
@AThrillingChase that they just aren't as special this way.
