Downtown streets will be filled with runners and spectators Sunday morning for the 19th annual Buffalo Marathon.

New this year is the Diaper Dash, a 26.2-foot crawl/walk for some of the race’s tiniest spectators. Sponsored by the John R. Oishei Children’s Hospital, the race is strictly for those athletes 2 years of age and younger.

There’s also a new text alert system for weather and traffic updates to keep runners notified of changing conditions on race day. To sign up, text 2019BuffaloMarathon to 33222.

The marathon is a four-day event this year, with yoga at the finish line on Franklin Street at 6 p.m. Friday kicking off the festivities and a Slow Roll at the Buffalo Naval Park on Memorial Day Monday to bring things to a close.

Here’s everything runners, spectators and those who want to avoid the crowds need to know about race weekend:
