Broomfield, Colorado’s exemplary Paul Derda Recreation Center is starting Nordic Walking classes on Thursday, May 3. I haven’t been able to find any info about the classes on-line, and I haven’t had a chance to phone either. I don’t know who is teaching them either. But the Daily Camera did indicate that the classes start at 8:30 a.m. and cost $32-$48 for an unspecified number of sessions. Those rates might be resident/non-resident fees or depend on whether or not poles are included. The rec center is at 13201 Lowell Boulevard, Broomfield. For more information or to register, call 303-460-6900.
