The Comrades Peak Long Run: Your Down Run Dress Rehearsal

Achieving success on the gruelling Comrades Marathon Down Run relies heavily on how you manage the peak long run. This session is the cornerstone of your overall preparation.

Under the guidance of experienced Comrades coaches, the peak long run is not treated as a brutal fitness test. It is treated as a controlled dress rehearsal. Its purpose is to remove uncertainty, test your race day plan, and bring you to the start line healthy, fresh and ready to perform.

Key Takeaways

• The peak long run is a dress rehearsal, not a fitness test.
• There is no need to run 60 to 70 km in training.
• Most runners should cap the peak long run at 40 to 50 km.
• Two Oceans can count as your peak long run.
• Long runs must be done at your slow Comrades race pace.
• Use the long run to test shoes, clothing, nutrition and hydration.
• Stop strength training 10 days before race day.
• Pack your tested race gear in hand luggage when travelling.

1. The Core Philosophy: Dress Rehearsal, Not a Fitness Test

The most important mental shift a runner must make is realising that the peak long run is not a test to prove you can cover the full Comrades distance.

Physiologically, there is no need to run 60 to 70 km in training to prepare for Comrades. Pushing to those extreme distances does not build extra fitness. Instead, it causes deep muscular damage that can require at least two weeks of recovery.

Capping your peak training run between 40 km and 50 km allows your body to recover within a single week. This protects your training consistency and keeps you healthy.

Running 70 km or more close to the race is a serious mistake. It risks leaving your best performance on the training road. It also increases the chance of starting the race with an active or hidden injury. This is a major risk because 68% of runners who start Comrades with an active or latent injury do not finish.

2. Individualised Distance Thresholds

Your peak long run distance should be matched to your running history, ultra experience and target finish time. The correct approach is scientific, individual and conservative.

Two Oceans or Ultra Marathon Profile

Target distance: 40 to 45 km. If you completed a major early ultra such as the Two Oceans Ultra, that race officially counts as your peak long run. On the traditional peak long run weekend, you should scale the distance back. Complete novices should run 40 km. Experienced or faster runners should run 45 km.

Standalone Marathon Profile

Target distance: 50 km. If your longest run during the training cycle is a standard marathon, your body still needs to move beyond the 42.2 km barrier. A 50 km peak run is entirely sufficient. Complete beginners and novice runners should limit the peak training run to 40 km.

Elite, Silver and Bill Rowan Contenders

Target distance: 50 to 55 km. Highly conditioned athletes can extend the peak long run to a maximum of 55 km. However, 50 km remains highly effective to avoid deep systemic fatigue while maintaining high quality weekly training.

3. Critical Pacing Rules: Pace the Mind and the Gut

The absolute rule of the long training run is that it must be done at your calculated Comrades race day pace. This should be the slowest and most relaxed running you do all year.

Avoid the Marathon Pace Trap

Running your long runs too fast is a costly error. Running at marathon pace breaks down muscle fibres, delays recovery and fails to prepare you for the metabolic demands of race day. The long run is not the place to chase speed. It is the place to build efficiency, patience and confidence.

Pace the Gut to Prevent Nausea

Running at a lower intensity changes the way your body digests and processes nutrients. If you only practise nutrition during faster training runs, your stomach will not be ready for race day intensity. Practising eating and drinking at your exact Comrades pace is essential gut training. It helps prevent nausea, vomiting and digestive shutdown during the race.

Build the Walk Break Habit

Use the peak long run to practise a structured walk break strategy. This makes the plan automatic on race day and helps delay muscular fatigue.

• Silver tier: Walk for 1 minute every 9 km.
• Bill Rowan and Robert Mtshali tiers: Walk for 1 minute every 6 km.
• Bronze and Finishers tiers: Take an active walk of 60 to 90 seconds every 3 to 6 km.
• On the hills: Use a strict rhythm such as 1 minute running and 1 minute walking. Walk before the road forces you to.

4. The Gear Dress Rehearsal Blueprint

Every item you plan to wear or carry on race day must be tested during your peak long run.

The 150 km Shoe Rule

Run your peak long run in the exact shoe brand and model you plan to wear on race day. The ideal race day shoe has around 150 km of use. At this point, the insoles have moulded to your feet, but the cushioning is still fresh and responsive. Avoid racing in shoes with more than 600 km of wear, as dead foam exposes your joints to excessive impact.

Carbon Plate Warning for Slower Runners

Runners at the middle or back of the field should avoid carbon plated shoes. As fatigue sets in, your gait often shifts to a heavier heel strike. In this state, the rigid carbon plate no longer helps with propulsion. It can act like a harsh lever, sending impact forces up the legs and increasing quad damage.

Chafe and Blister Protocols

Use the long run to identify hot spots before they become race day problems. For the toes, wrap each toe elastically and apply Vaseline properly. For the heels, apply elastoplast, add a generous layer of Vaseline and wear a thin sock. Use seamless running underwear to eliminate raw chafing.

Sports Bra Science

For female athletes, a professionally fitted, supportive and adjustable sports bra is a non negotiable performance tool. During running, the breasts can bounce 10 to 12 cm in multiple directions per step. A high quality sports bra improves running economy, with a performance advantage of nearly 3 km over the Comrades distance.

The Sunscreen Eye Line Rule

Apply sunscreen only below the eye line. Wear a cap to stop sweat from washing sunscreen into your eyes. This prevents painful stinging and a bitter taste during the race.

5. The Nutrition and Fuelling Blueprint

Avoid the Expo Trap

The race expo is full of exciting new gels, bars and drinks. Trying these on race day for the first time is a common cause of nausea, vomiting and DNFs. Use your long run to test the exact brands and flavours you plan to use in the race.

Fuel Early and Use Water with Gels

Begin taking in carbohydrate energy from the start of the run. Aim for at least 50 grams of carbohydrates per hour. Always wash gels down with plain water. Concentrated gels or hypertonic sports drinks without enough water can cause osmotic diarrhoea, drawing water into the gut and triggering sudden cramping.

Practise a Solid Food Strategy

For runners who will be on the road for 10 to 12 hours, sweet gels are often difficult to sustain. Use the long run to practise eating small amounts of salty, easy to digest solid food. Good options include boiled baby potatoes, potato wedges, banana bread, or small quarters of Bovril sandwiches. The goal is to drip feed the body with usable energy while keeping the stomach settled.

6. Strategic Timing and Transition to the Taper

The timing of your peak long run matters. It must be close enough to the race to be useful, but far enough away to allow full recovery.

• Beginners and novices: Complete a 40 km peak long run around 26 or 27 April.
• Experienced ultra runners: Complete a 50 km peak long run around 3 or 4 May.
• Silver and elite contenders: Complete a 55 km peak long run around 10 or 11 May.

After the peak long run, transition into a structured three week taper. Keep your midweek routine the same at three weeks out but reduce the weekend long run to a maximum of 20 to 25 km. At two weeks out, reduce overall volume to 75% of baseline and limit the weekend run to a comfortable 8 to 12 km. In race week, cut the previous week's load by another 50% and do only a few short, easy runs.

All resistance strength training must stop completely 10 days before the race. Replace strength sessions with short mobility, stretching or foam rolling routines.

7. The Post Run Checklist and Travel Hack

Immediately after your peak long run, sit down and write a complete race day checklist while your physical sensations are fresh. Include every item from head to toe: cap, sunglasses, sports bra, top, underwear, shorts, socks, shoes, plasters, Vaseline, nutrition, and hydration plan. This checklist becomes your packing guide during race week.

If you are travelling to the race, pack your tested race gear in your hand luggage. This is especially important for shoes, socks and sports bra. Checked baggage can be lost or delayed. If your tested gear stays with you, your race plan remains secure.

Comrades Peak Long Run FAQ

How long should the Comrades peak long run be?

Most runners should cap the peak long run at 40 to 50 km. Elite and very experienced runners may go up to 55 km, but 50 km is still highly effective.

Should I run 70 km before Comrades?

No. Running 70 km close to the race creates deep fatigue and increases injury risk. It does not provide extra fitness that justifies the recovery cost.

Does Two Oceans count as my peak long run?

Yes. If you run the Two Oceans Ultra, that race counts as your peak long run. Your next traditional peak long run should be reduced to 40 km for novices or 45 km for experienced runners.

What pace should I run my Comrades long run?

Use your calculated Comrades race day pace. This should be the slowest and most relaxed running pace of your training cycle.

Why must I walk during long runs?

Walk breaks reduce muscular fatigue, protect your legs and make race day pacing easier to manage. Practising the strategy in training makes it automatic during the race.

What if my gear is lost during travel?

Always pack your tested race gear in hand luggage. Your shoes, socks, sports bra and key clothing items should never be placed in checked baggage.

Final Thought

The Comrades peak long run is not about proving your fitness. It is about refining your race plan, protecting your body and building calm confidence. Keep the distance controlled. Keep the pace slow. Test every detail. Arrive healthy. If you treat the peak long run as a dress rehearsal, you give yourself the best possible chance of reaching the finish line in Durban.
