Running form check for Couch to 5K runners

Your Couch to 5K form should be short steps under your hip, a tall chest and slow enough pace to talk. That is it for the first weeks. The plan tells you how long to run. Nobody tells you how to run. A phone clip fills that gap, and the best time to look is before the run intervals get long enough to make bad habits stick.

What Couch to 5K form problems usually are

Couch to 5K runners run slowly, which is right. But slow running with an untrained body leads to the same few patterns.

1. The walk-run shuffle. Steps are long and slow, close to a fast walk. The foot lands well ahead of the hip with a straight knee. Cadence is often under 155 steps per minute.
2. Fading posture. Week 1 intervals are 60 seconds. By week 6 they are 20 minutes or more. The chest drops and the head pokes forward when the run gets long. Form at minute 15 is what matters, not minute 1.
3. Tense arms. New runners hold the arms high and tight, hands near the chest. That lifts the shoulders and shortens the breath.

Shin pain and knee soreness are common complaints in weeks 4 to 6, when the run time jumps. Reaching forward with the foot is often linked with both, though a video cannot tell you the cause. It can only show you the stride.

What to film

Film a side view at the end of a run interval, not the start. If your plan says run 8 minutes, set the phone up so you pass it in the last minute. That shows the form you actually hold when tired.

Phone at hip height on a bench or a wall, 6 to 8 metres from where you run past. Flat ground, good light, nobody else in frame. Run at your usual Couch to 5K pace. 10 to 20 seconds is enough. See how to film yourself running for the details.

Do this once at week 2 or 3, and again at week 8 or 9. Two clips, eight weeks apart, tell you more than a clip every day.

What Caden shows you

A form score out of 100, with 85 and above excellent, 75 to 84 good, 60 to 74 fair and under 60 needing work. Then six dials. where your foot lands, knee bend on landing, knee bend at push-off, upper body lean, arm bend and head position. Plus cadence in steps per minute.

For a Couch to 5K runner, read the dials in this order.

• Where your foot lands. How far ahead of your hip the foot touches down. If the note says "Reaching too far ahead", start here.
• Upper body lean. Torso lean in degrees. A slump shows as too much lean from the waist.
• Cadence. Under 160 at your pace usually means long slow steps.

Tap Breakpoints to see the freeze frame at foot strike with a skeleton over your body and the landing ankle circled. That one picture is usually enough to make the problem obvious. The coach's tip gives one cue per dial in plain words.

A sample 4-week plan for weeks 5 to 8 of Couch to 5K

Caden builds a 4 or 8 week plan on the Exercises tab from your lowest dials, three short sessions a week at a session length you choose. Fit the sessions on your rest days. None of them add running time to your plan.

Weeks 1 and 2 of the plan: land under you.

• A-march, 3 × 30 seconds.
• Slow calf raises, 3 × 10. These help the shin and calf handle the longer intervals.
• Single-leg balance, 2 × 30 seconds each side.
• Dead bug, 2 × 8 each side.
• On each run interval over 5 minutes, use the cue for the last minute.

Short, quiet steps.

Weeks 3 and 4 of the plan: hold it when tired.

• A-skip, 3 × 20 metres, after your warm-up walk.
• Quick-feet strides, 3 × 20 seconds, only if your legs feel fine.
• Glute bridge, 3 × 10.
• Ankle rocks, 2 × 10 each side.
• Use the cue for the last two minutes of every run interval.

Film again at the end of week 8 or 9 and open Before and after in Stats.

What Caden will not do for you

It will not replace the Couch to 5K plan. It says nothing about how long to run or when to move up a week. Keep following your plan.

It will not tell you if you are injured or why. A video shows the stride, not the cause of pain. If a shin or knee hurts on more than a couple of runs, rest it and see a clinician.

It cannot measure force or pronation. It is a 2D view from a phone. It sees landing, lean, knee bend, arms and head. That is enough to fix the shuffle.

How to do it in Caden

1. Open Caden and tap Run a new analysis.
2. Set the phone at hip height 6 to 8 metres from your path. Run past in the last minute of a run interval for 10 to 20 seconds.
3. On the results screen, read the Where your foot lands dial and the cadence number.
4. Tap Breakpoints, then Foot strike. Check whether the circled ankle sits ahead of the hip.
5. Open the Exercises tab and do the plan sessions on rest days.
6. Re-film in week 8 or 9 and open Before and after in Stats.

FAQ

When in Couch to 5K should I check my form?

Week 2 or 3 for a baseline, then week 8 or 9 when the intervals are long. Earlier than week 2 and the runs are too short to show your real form.

Should I change my form in the middle of the plan?

Change one thing, with one cue, for short stretches of a run. Do not rebuild your stride while also adding run time every week. The drills on rest days do most of the work.

My shins hurt in week 5. Is it my form?

A video cannot tell you that. Reaching forward with the foot is often linked with shin pain, so check the foot landing dial. If the pain lasts more than a few runs, rest and see a clinician.

Does Caden work if I run really slowly?

Yes. It measures where the foot lands and how you hold your body at any pace. Slow, walk-like running is exactly what it was built to spot.
