With all the changes happening for the marathon in Chicago a few days from now, I wonder what the future holds for additional security at Run Disney events.

Here are the changes for this years Marathon in Chicago.

With just days until the 36th Chicago Marathon, both runners and spectators are gearing up for heightened security at Sunday's race.
Though race officials don't specifically reference the Boston Marathon bombings in the 2013 updates to race security, the April tragedy that killed three people is still fresh in the minds of police, organizers and runners.
Security will be tighter at Sunday's race on account of five new changes:
No Packet Pick-Up Proxies: In years past, runners could send someone like a family member to pick up their racing bib and marathon packet at the Friday-Saturday expo at McCormick Place. This year, however, entrants will have to show up in person to claim their bib, chip and other necessities.Clear Bag It: Runners can only bring materials that fit into a clear, plastic event-issued "Participant Bag" to the starting line. Previously, runners could bring just about anything -- spare clothes, food, electronics, keys -- in whatever bag or luggage they wished and check it at the starting corral for pick-up after the race.
Just Like The Airport -- Long Security Lines: Though marathon participants have always been subject to a quick once-over bag check, this year runners will only be able to get into the starting point at Grant Park after passing through one of four designated security and bag screening checkpoints off of Michigan Avenue. Runners who opt to skip bringing a bag at all can speed through express lines.
Check, Please: Spectators will have to go through bag screening and checkpoints to access the "reunion" area in Grant Park's Butler Field. Additionally, DNAinfo Chicago reports Chicago police will be checking spectators' backpacks around the race route, as they did during the Chicago Blackhawks championship rally earlier this summer.
Smell Test: Though the marathon officials make no mention of their presence on the course, police say they plan to use bomb-sniffing dogs along the marathon route Sunday.
