Friday is the last day to register for the Coffeyville Recreation Commission's "50 in 50" Challenge.

The challenge is a virtual, "at-home" mission that tasks participants with walking, jogging or running 50 miles in 50 days. Participants may also follow a workout routine, converting time spent into miles as necessary.

The cost to register is $15, and may be done either online at the CRC website or at the CRC office.
