Have questions about the sizing of your jacket?

Runners that register for Grandma’s Marathon before December 31st will receive a commemorative performance jacket included with your entry fee.

This durable raglan style, anti-pill, 100% poly fleece-lined jacket is great for all occasions and provides warmth without weight.

Jacket features include side zip pockets, thumb slits, and reflective piping on the front zipper. The jackets are gender-specific and semi-fitted, so it is recommended to order one size down for a tight fit. Please refer to the sizing chart when ordering.

All jackets will be shipped in early 2018.


Want to change the size of your jacket?

Please refer to the steps above to login into your Race Roster account and update your jacket size.
