Every race can be just a little bit different. And the same is true of every Health and Fitness Expo and Runner Packet Pickup. There really is only one way to make sure you are good to go on the day of the event.
Action 397 - Follow Instructions.
The La Jolla Half Marathon mails a preprinted postcard to each registered runner a week before the race. Each runner must bring that postcard, plus their photo identification, to the Expo the day before the race. If you do that, you can be in and out of the expo and on your way in a matter of minutes.
But if you fail to follow instructions, you can enjoy a long line outside of the venue, like these people.
Yep. They are standing in the "no postcards" line. After they sort out whatever mess that is, they will then be allowed into the expo to stand in another line.
Follow instructions. It's generally a good idea.
