The Peak Weeks Are Here

If you are training for a spring marathon, half marathon, or any distance race between now and May, this is the part of the cycle where things get real. The long runs are getting longer. The midweek sessions are getting harder. The fatigue is building. And a huge number of runners are about to sabotage their own race. Not through lack of effort, but through mistakes that feel logical at the time.

1. Dropping Strength Training Too Early

Around six to eight weeks out from race day, the running volume peaks and the natural instinct is to cut the gym. Here is why that is a mistake: strength training protects the structures that absorb impact during long runs. Research consistently shows that runners who maintain strength training throughout their marathon block have better running economy and lower injury rates. Reduce gym volume by 30 to 40 percent during peak running weeks, but do not eliminate it.

2. Running Your Easy Days Too Hard

When runners feel fit, they let their easy pace creep up. For hybrid athletes, this problem compounds because you are also recovering from gym sessions. If Monday is heavy squats and Tuesday is supposed to be an easy 8km, running it at the wrong pace turns a recovery day into another stress day. If you cannot comfortably hold a full conversation, you are running too fast.

3. Ignoring the Taper

The taper is the two to three week period before race day where you reduce training volume. For hybrid athletes, the taper applies to the gym too. Reduce lifting volume significantly in the final two weeks. This is not the time for personal bests in the squat rack.

4. Fuelling Like a Lifter Instead of a Runner

During peak training weeks, a marathon runner needs 6 to 10 grams of carbohydrate per kilogram of body weight per day. Your long runs are dress rehearsals for your fuelling strategy. Start testing your race nutrition now.

5. Neglecting Sleep During Peak Weeks

Sleep is not a luxury during marathon training. Research shows that getting less than seven hours consistently during heavy training blocks increases injury risk and reduces performance on race day. Prioritise sleep the same way you prioritise your long run.

6. Adding Volume When You Should Be Adding Recovery

By six to eight weeks from race day, the foundation has been laid. Adding volume in the final weeks is the fastest route to overtraining and overuse injuries. Consistency over the full training cycle matters far more than any single week of heroic volume.

7. Not Having an Integrated Plan

Most runners who also lift have two separate plans that do not talk to each other. The result is that Tuesday's heavy deadlifts destroy your posterior chain, Wednesday's tempo run suffers, and Saturday's long run becomes a survival exercise. This is not a failure of effort. It is a failure of structure.

How Edge Fixes All Seven

Every mistake on this list exists because running and lifting are being treated as separate activities instead of one integrated system. Edge was built specifically to solve that problem. It programmes your strength and running as a single plan, sequences your week intelligently, and gives you access to real coaches who can see your full training picture.

Start your free 7-day Edge trial and run your best spring race without sacrificing the strength you have worked so hard to build.
