Running enthusiasts can celebrate the arrival of spring with two half-marathons -- one through the rolling vineyards of Livermore and the other through the bucolic streets and trails of Pleasanton.

The inaugural Livermore Half Marathon on Saturday will take runners on a 13.1-mile trek through city streets and California's oldest wine region. The route starts and ends on the newly redeveloped First Street that's enjoyed an economic surge in recent years.

Runners will get a commemorative wine glass they can use to sample wines from 13 local vintners that will be set up as part of the post-race festivities that also include live music, craft beers and artisan chefs. The event will feature a 2.5-mile family run downtown that's promised to end before the first runners finish the half-marathon route. The family fun run is $25 per person.

The half-marathon is $99 per person. The last day to register is Friday. The run is hosted by a private for-profit company. Visit runliv.com for more information and to register online.

The second annual Pleasanton Run for Education will be held April 13 and is a fundraiser for all Pleasanton public schools. The half-marathon route starts at the Alameda County Fairgrounds and takes runners on city streets and dirt trails before ending back at the fairgrounds.

The event also features a 5K race and a kids challenge. Entry fees vary depending on the race and date of registration. There's a discount for runners who register by April 9. Last year's run raised $58,000 for Pleasanton schools through the Pleasanton Partnerships in Education foundation. Organizers hope to far exceed that figure this year.
