Wednesday in Saratoga

In stakes racing at Saratoga Race Course, we’ll see the 20th running of the $200,000 Lake George. Historians would tell you about Lake George’s significance in the British defeat at Saratoga. Upstate residents would talk about how the lake’s clear waters are surrounded by soft green mountains. Anyway, point made. Post time is 1 p.m.

It’s the second day of the 173rd Saratoga County Fair. The secret to the electric energy of the summer fair is its competitions — kind of quirky competitions, actually — like best blueberry pie, or fastest sheep shearer. Up today is a LEGO contest with the theme “fun at the fair.” True, they’re only LEGOs, but there’s something fascinating in seeing a familiar set of materials turn into an architectural marvel. You can look at the entries between noon and 4 p.m. in the Saratoga County Fair Family Center for no additional cost, though admission to the fair is $10.

It’s Latino American Day at the race course’s Saratoga Pavilion, beginning a series of weekly cultural heritage celebrations at the race course. This means you can add a delicious assortment of ethnic dishes to the variety of food already offered at the track. The event doesn’t end with food. You’ll also see traditional dance, music, and crafts. There’s even a contest (yes, the kind with prizes) for picnic spots in the race course’s backyard. To win, make yours sing with a festive arrangement of Latino-American decor. The event runs from 11 a.m. to 4 p.m.

Shmaltz Brewing Co. at 6 Fairchild Square in Clifton Park will host Hump Day Happy Hour from 5 to 8 p.m. In the “free things” category, expect samples of locally brewed beers and live music from the acoustic pop singer Steve Smith. Four food trucks will also be open for business: Eat Good Food, Slidin’ Dirty, The Crisp Cannoli, and Hungry Traveler. Sausage rolls from Eat Good Food, by the way, come smothered in a homemade sauce of local Roma tomatoes simmered with herbs and spices for 12 hours.

If you have a high pain tolerance in your ear drums, you’re the intended audience for the Rockstar Mayhem Festival at SPAC. Rockstar Energy Drink, the show’s namesake, has assembled an explosive lineup of 17 artists, including Avenged Sevenfold, Korn and Asking Alexandria. Tickets start around $40 at Livenation.com. The show begins at 1 p.m.

Is anything more relaxing than smooth blues under low lights? Caffe Lena is hosting its monthly Acoustic Blues Jam Open Mic Night. The legendary coffeehouse is right in downtown Saratoga. Because the night’s lineup is determined by the names pulled out of a hat, expect a wide range of ages and talent. Tickets are $5 and sold at the door.

Another Wednesday brings another Saratoga Farmers’ Market at the High Rock Park pavilions, located at 105 High Rock Ave. in Saratoga Springs. The market lasts from 3 to 6 p.m.
