Your build to race day
Taper
Tapering for the Houston Marathon
Start the taper two to three weeks 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 is flat, so pacing decides the day: rehearse your goal pace in short segments during race week. With the race on January 17, 2027, your taper starts around December 30, 2026.
