With so many events going on this spring, I can barely keep up. Here are a few of note this weekend:Want to get fit with your pup? The 5K9 Walk Run, presented by the Petco Foundation and Purina Pro Plan, features a 5K and 1-mile runs for you and your pooch. Proceeds from the May 11 event, which includes a healthy living expo for humans and pets, will benefit Austin Pets Alive! Packet pickup and race day registration is from 6-7:30 a.m. Saturday at Walter E. Long Metropolitan Park, 6614 Blue Bluff Road. The 5K starts at 8 a.m; the 1-mile starts at 9 a.m. The Purina Pro Plan Performance Team, which features professionally trained rescue dogs, will give demonstrations all morning. Anyone without a pet companion can borrow a shelter dog for the race. For more information or to register, go here. www.5k9walkrun.comWant to get dirty? At the REI Muddy Buddy, teams of two will compete with or without a bike in an off-road adventure race with wacky obstacles and a notoriously glorious mud pit, which all teams must crawl through before crossing the finish line. Afterward, there’s a post-race beer garden. Kids age 4 to 11 can compete in a Mini Muddy Buddy, with a short obstacle course and the same mud pit. A portion of proceeds benefit the Prostate Cancer Foundation. The May 11 event takes place at Flat Creek Crossing Ranch in Johnson City.

What could be better than racing a 5K then sitting down to a plate of Tex Mex and a margarita? Proceeds raise money for The Trail Foundation, which helps maintain and improve the Butler Trail at Lady Bird Lake. Porjects include new restrooms, improved lakefront gathering areas and native tree plantings. Tickets are $30 for the 5K only or $95 for both the 5K and party. Prices increase on June 10 if tickets are still available. For more information go here. www.TheTrailFoundation.org.
