I dropped by IFEMA to pick up my race materials for EDP/Rock n Roll Madrid Half Marathon. The convention hall is 3-4 subway stops from Madrid's international airport, which was perfect since it was on the way to the center of town. A cab from IFEMA was about 15 min to the center of town, and I think the fare was about 12€ (don't quote me on that price).
Overall, I found my experience to be pretty positive. The convention hall is very large (at least 3 HUGE pavilions), very spacious, and clean. The organizers of the made a pretty well-oiled bib pick up process. read more
