When America’s fastest cars return to New Hampshire Motor Speedway on Aug. 14, race fans will already be familiar with the off-track activities of former Boston-area resident and three-time IZOD INDYCAR Series champion Dario Franchitti.

Franchitti will debut a blog on Boston.com Monday, March 21, giving fans a rare glimpse into the lifestyle of the reigning series champion. For the rest of the season, the blog will run every Tuesday following an IZOD INDYCAR Series event.

Franchitti, a two-time Indianapolis 500 winner, is no stranger to “The Magic Mile.” He raced here in the June 2008 NASCAR Sprint Cup Series and NASCAR Nationwide Series events during his only season of NASCAR racing for team owner Chip Ganassi.

Franchitti’s most recent visit to the 1.058-mile oval came last year when he helped officials announce INDYCAR’s return to New England by running three exhibition laps prior to the LENOX Industrial Tools 301 NASCAR race.

A native of Scotland, Franchitti and his wife, actress Ashley Judd, lived in Cambridge, Mass., for a year while she earned her graduate degree in public administration from Harvard University.

Tickets for all three of New Hampshire Motor Speedway’s major motorsports events, the NASCAR Sprint Cup Series LENOX Industrial Tools 301 on July 17, the IZOD INDYCAR 225 on Aug. 14 and the NASCAR Sprint Cup Series SYLVANIA 300 on Sept. 25, are now available.
