"The Kohanim planned it like a military operation, training for months, consulting leading rabbinical authorities on every halachic (Jewish legal) detail, preparing backup loaves in case of failure, and assigning each participant a precise role. And then, on Shavuot — a day when the Temple Mount was officially closed to Jews — they ran barefoot across the holy site, dodging Arab worshippers hurling plastic chairs and police officers trying to tackle them, and waved the Shtei HaLechem (the Two Loaves offering) for the second consecutive year. Thirteen of the fourteen participants were arrested. The loaves are in police custody. And the men who carried them say they felt nothing but joy."

It was very hard to run with priestly garments and the tray.” FULL STORY at above link. (5 kilos is about 11 lbs.)
