In case eating snowballs on a hot summer day isn’t rigorous enough for you, over fifteen charity runs and walks have been booked for May. The month kicks off with the ONS Foundation/Pfizer Oncology Fun Run Walk and Wheelchair on May 5. Soon after, at least two running events will be available to New Orleans patrons every weekend. If you aren’t much of a runner, or the idea of running in a large group makes you nervous, don’t be intimidated. Most events extend an invite to athletes of all levels.
