Your build to race day
Taper
Tapering for the BOLDERBoulder
Start the taper seven to ten days before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course rolls, so keep one short session on undulating ground in the first taper week. With the race on May 31, 2027, your taper starts around May 22, 2027.
