The cold bomb has dissipated and the weather – surprise! – looks unseasonably warm and possibly a little wet for Sunday’s 3M Half Marathon.

According to KVUE, we’ll see a low of 57 and a high of 72, with a 50 percent chance of rain on Sunday.

Nearly 7,000 people have registered for the race so far, and organizers are expecting the largest field in race history. Registration closes Saturday.

The 3M typically unfolds fast and furious, on a mostly downhill, point-to-point course that starts on Stonelake Boulevard in North Austin and finishes near the Texas State Capitol. That’s a 300-foot elevation drop, which can mean sore quads for runners not used to running long stretches of downhill. (Yes, I know this from experience.)

The race starts at 7:30 a.m.  A finish line festival will include a beer garden, music and food trucks.

Martin Fagan holds the men’s course record of 1 hour, 1 minute and 5 seconds, set in 2009. Jacquline Nyetipei holds the women’s record of 1 hour, 9 minutes and 35 seconds, set in 2008.

This year’s elite field includes Anita Perez, Matt McCurdy; Brooke Torres; Cate Barrett, Kaitlyn Johnson, Heather Zytkewicz, Randi Burnett, Joey Whelan, Natasha Van der Merwe and Edie Stevenson.

Also expected to compete is triathlete Laurie Allen, who was paralyzed in a fall three years ago. She’ll race on a hand cycle.
