Run for the Arb is the annual 5K family run/walk through the Arb and is sponsored by Matthaei Botanical Gardens and Nichols Arboretum. It's also a fundraiser to benefit Matthaei-Nichols and a great way to see the Arb decked out in fall colors. The race begins at the James D. Reader, Jr. Urban Environmental Education Center at the Arb’s Washington Hts. entrance, 1610 Washington Hts., Ann Arbor. Registration includes t-shirt and timing. Register your dog and receive a bandanna for Fido.
