Bib pickup

Bib pickup is on race day at the venue reception. No advance postal delivery of bibs or entry materials.

Bibs are collected in person on race day, and race details are sent by email only. There is no indication of overseas entry support, and the in-person bib pickup requirement makes this effectively inaccessible for overseas runners.
