Add these fun Halloween-themed events to your calendar…Join Rogue Running, 410 Pressler Street, for the Haunted Halloween Hustle tonight, Oct. 26. Runners will take a running tour of Austin’s most haunted spots, learning about piano playing apparitions, unidentified graves, shrieking from the attic and ghosts on the capitol grounds. Routes of 3, 5, 7, or 10 miles are available, with a costume contest and adult beverages to follow. Event starts at 8 p.m. Cost is $10. Register here. Head to NLand Surf Park, 4836 East Highway 71 in Del Valle, on Saturday for trick or treating, free yoga, live music, beer and queso specials – and, of course, surfing in the 14-acre lagoon. (Worried about the cold? Don’t. Wetsuits are available for rental.) Trick or treating tours will start at 1:30 p.m., 2:30 p.m. and 3:30 p.m. A Halloween-themed selfie station and Halloween-themed sandbox toys for kids are also planned. Costumes are encouraged (but not while surfing). For more information go here.
