Hundreds of Manor students (and parents) are hoping to find their way in the Guinness Book of World Records after participating in an around-the-country coordinated jumping jack event going after the record for the most jumping jacks done in one minute in one day, sponsored by First Lady Michelle Obama.

The worldwide challenge is part of the first lady's Let's Move campaign to create awareness and combat childhood obesity. More than 20,425 people must perform jumping jacks for one minute from noon Tuesday through noon Wednesday to break the current world record.

The jumping jack effort came after students around Marin - including those at Manor and in the Ross Valley - walk, biked and rolled to school, with a firefighter escort, as part of the annual effort to get out of cars.
