At the Big D Climb, the biggest in North Texas, participants race up 70 stories of stairs at Bank of America Plaza, in Downtown Dallas, to raise money for blood cancer research. January 26 will mark the event's 11th year and the goal is to sell out the climb and raise more than $350,000 for The Leukemia & Lymphoma Society. More than 1,000 raced last year to raise close to $300,000.  The Opening ceremony begins at 7:30am at the Bank of America Tower in downtown Dallas.

Those that don't want to try it alone can form a team and challenge friends, family and co-workers to a race you to the top by using the “create a team" link on the registration page. Racers must be at least 7 years old to participate. For safety reason, children are not able to be carried.

Location: 901 Main St., Dallas. For details, visit lls.org/pages/ntx/bigclimb.
