Registration is open for the 21st Annual St. Paddy’s Day 5K Run/2-Mile Walk, to be held Saturday, April 18, at the Salisbury Elks Lodge. The first 200 to register are guaranteed an event T-shirt.

Special guest this year is state Delegate Carl Anderton as the honorary chairman.

New this year: Runners will be timed using electronic chip timing for immediate results and accuracy. This is the same system used for running events such as the Boston Marathon!

The theme of the run/walk is “Racing For a Reason.” All proceeds will support MAC Inc., programs and services for those living with Alzheimer’s Disease and their caregivers.

The scenic 5K course will wind through the Salisbury zoo and park.

Check-in and late registration will begin at 2 p.m.; the run/walk will step off at 3 p.m. The cost is $25 for walkers; $30 for runners in advance and $35 for runners the day of the race.

Online registration (runners only) will close at 11:59 p.m. on Wednesday, April 15. In addition, mail-in registration must be postmarked no later than Monday, April 13. Please note: no dogs are allowed in the zoo portion of the 5K route.

Overall awards will be presented to the top three male, female and masters finishers; awards also will be presented to the top three male and female finishers in various age divisions.

An awards party following the race is free to registered participants; guests can attend the after-party for $5, $15 for families of three or more, and children under age 5 will be admitted to the party free. The party will feature free food, door prizes, a 50/50 raffle and live auction.
