Spring has always meant 5-K racing season in Austin and even though the number of races has diminished, there are still several races left such as the Purple Stride 5-K at Arbor Trails in south Austin (May 7th), the Daisy 5-K at Camp Mabry on May 28th and the Stars and Stripes 6-K, also at Camp Mabry (May 30). This Sunday (May 8) is the biggest and best of the bunch: The third annual Silicon Labs Sunshine Run.

This race is the successor to the much loved spring classic: The Bun Run. But that race has moved on and the Sunshine Run has taken its place, put on by the same group (the Young Men’s Business League of Austin) on the same exact course, similar race date and same beneficiary—the Austin Sunshine Camps.

Unlike the Bun Run which was mainly a 5-K, the Sunshine Run has a 5-K and a 10-K. (The final year of the Bun Run a 10-K was added.) A record field of more than 1500 runners are expected on Sunday and the field is evenly divided between the two distances. There is prize money ($350-$100-$50 for the first three guys and gals, but the cash awards are only for the 10-K.

Both races begin on Sunday morning at 7:30 at the starting point along Auditorium Shores, near the corner of Riverside and S. 1st Street. The Kids K will begin at 9 a.m.

The Sunshine Run course is one of the most familiar and fastest in Austin. Long known as the Dog Pound Loop, the course starts on Riverside and the South 1st Street Bridge, opposite the Long Center. Runners will head north for a couple of hundred meters over the bridge before heading west and taking the plunge on Cesar Chavez toward Austin HS. At Stephen F. Austin, just outside Austin High, the course will swing back on Cesar Chavez along Lady Bird Lake (and the always tricky three-tiered hill) before crossing over the South 1st Street Bridge and finishing up on Riverside.

The 10-K follows the same course as the 5-K, but instead of looping around the Dog Pound, the runners will simply continue past Austin HS and then head west on Lake Austin Boulevard before doubling back.

Packet pick up is at Ready to Run (3616 Far West Blvd.) on Friday (10-7) and Saturday (10-5). There will be race day packet pick up and registration, beginning at 6 at the race site, right in front of the Long Center.

There will be free bike valet parking and bag check at the race. There is plenty of parking available near the race site at various locations, some free and some with parking rates.

If you choose to use a Lyft ride to the start, Lyft will donate $10 to the Sunshine Camps for everyone who downloads the Lyft app and enters SUNRUN in the payment area and takes their first Lyft ride.

Again, the 5-K and 10-K begins at 7:30 at Auditorium Shores. We’ll have complete coverage at Texas Running Post—hopefully with results—on Sunday morning.
