Strength, cross-training and tapering: fit support work into the plan
Strength and cross-training supplement running rather than replace it; a taper is not complete rest. Keep some intensity and frequency, reduce total volume, and let recovery and sleep catch up.

Where strength work fits
CDC adult guidance recommends muscle-strengthening activity on at least two days a week, covering the major muscle groups. For runners, strength work can support muscle and tendon capacity, but the evidence that it prevents every running injury is not uniform; training load, recovery and individual differences also matter.
When starting, one or two sessions a week with a few stable exercises is more useful than a long list. Place lower-body strength where it does not compromise a key quality session, or on an easy day with several hours between sessions. Do not add unfamiliar heavy lifting during race week.
Cross-training is not a substitute for running
Cycling, swimming and elliptical work can add low-impact aerobic volume and can help when injured or when surfaces are poor. But running-specific load, landing mechanics and coordination cannot be fully replaced. Treating cross-training as extra volume rather than recovery can let total load spiral.
If pain is the reason for switching, first clarify the cause and what you can tolerate, with medical or sports-professional input when needed. Cross-training should not be used to run around steadily worsening pain.
A taper is not complete rest
A systematic review and meta-analysis of 14 studies found that tapering improved time-trial and time-to-exhaustion performance. A common effective pattern reduced training volume by about 41–60% while maintaining intensity and frequency, with tapers lasting up to about 21 days. Some studies found a larger effect when tapering followed pre-taper overload training.
That does not mean copying one percentage. Amateur runners can start with a gradual one-to-three-week taper: keep a little tempo or short intervals, reduce long runs and total mileage, and prioritise sleep and food. The taper is not a window for “catching up” with extra training; adding sessions can spoil the recovery it is meant to create.
Race week
The goal of race week is to remove fatigue, not to squeeze in one last stimulus. Reduce volume to a comfortable low, keep short easy runs and a few brief accelerations, and avoid new shoes, new fuel or a new route. Sort out transport, bib, kit and nutrition in advance so attention is left for the race.
If tapering leaves you more tired, sleeping badly or in pain, check total load, stress and health rather than adding more training.
What this page does not provide
This page does not prescribe an individual strength programme, treat injury or give an exact taper percentage. Persistent pain, fatigue, a history of injury or conflicting race goals deserve assessment by a qualified coach, clinician or sports professional.
Sources and scope
Adult strength guidance follows CDC and ODPHP; taper effects and volume ranges follow the PLOS ONE systematic review and meta-analysis; the limits of running-load and injury evidence follow a systematic review. Study samples and events differ, so this page offers organising principles rather than a guaranteed plan.
Sources and evidence
Adults need at least 150 minutes of moderate-intensity activity weekly, or an equivalent combination. Adults also need two days of muscle-strengthening activity each week. Activity can be spread out and broken up; some activity is better than none.
The meta-analysis included 14 studies and found significant improvements in time-trial and time-to-exhaustion performance after tapering. A taper that reduced training volume by 41-60%, maintained training intensity and frequency, and lasted up to 21 days was associated with improved time-trial performance. Tapering combined with pre-taper overload training showed a larger effect on time-trial performance than conventional tapering. The authors note that tapering practices still need individual adaptation.
Across 36 studies and 23,047 runners, 26.2% reported a running-related injury. Evidence linking weekly distance, duration, frequency, intensity or recent changes to injury was conflicting. The authors caution against recommending one optimal training progression for every runner.
Adults gain substantial health benefits from regular physical activity. The guidelines recommend moving more and sitting less throughout the day. For substantial health benefits, adults need at least 150 to 300 minutes a week of moderate-intensity aerobic activity, or 75 to 150 minutes a week of vigorous-intensity aerobic activity, or an equivalent combination. Adults should do muscle-strengthening activities on at least 2 days a week.
