Understanding the Comrades Marathon Challenge
The Comrades Marathon is one of the world's oldest and most respected ultramarathons, spanning 89km between Pietermaritzburg and Durban in South Africa. This is not a standard road marathon—it's a test of endurance, mental resilience, and strategic pacing over nearly twice the distance of a conventional marathon. With 1400m of elevation gain and five major hills punctuating the course, runners face an undulating terrain that demands specific preparation. The race features an alternating up/down format year to year, meaning the same hill that drains your legs in one direction becomes a descent the next year. This variation makes understanding the actual course profile for your specific year critical. The 12-hour cutoff is absolute, adding time pressure to an already demanding event. Most runners take 9-11 hours to complete the distance, meaning pacing discipline and steady effort are essential from gun to tape. This is an ultramarathon that rewards patience, preparation, and proper fueling—not speed.

Comrades Marathon Race Day Tips
1Start conservatively—the opening 20km feels easier than middle sections, resist surging with crowds
2Pace the hills strategically: walk portions if needed, save leg power for descents where you can gain time
3Establish a fueling rhythm at 250-300 calories per hour with 500-750ml fluid intake hourly
4Use aid stations mentally and physically: walk through them, reset your mind, check your body
5Run tangent lines on flat sections to save distance; save energy on technical descents where others slow
6Monitor your cushion to the 12-hour cutoff constantly—be willing to adjust effort if falling behind
7Practice your nutrition strategy on long training runs; never try something new on race day
8Expect a mental low point around 60-70km; have a mantra and break the race into smaller chunks
9Protect your feet: change socks at mid-race aid stations, use blister prevention early
10Embrace the crowd support through the Durban finish; the energy carries you through final fatigued kilometers
Essential Gear for Comrades Marathon
Trail/road hybrid shoes with good cushioning and rock plate protection for varied surfaces
Race-specific hydration pack or hand-held bottle system (aid station reliance alone is risky)
Anti-chafe products for nipples, inner thighs, and underarms (89km is a long time)
Electrolyte drink mix and energy gels matching your race-day fueling plan
Compression or moisture-wicking socks to manage blister risk over ultra-distance
Race belt or small pack for fuel, phone, and emergency supplies between aid stations
Sunscreen and lip balm with SPF (South Africa sun at altitude is intense)
Watch or GPS device for pacing, distance, and time management against the 12-hour cutoff
Capri tights or shorts that won't chafe; test thoroughly in training
Lightweight, breathable race top; layering options if you're running in early June with variable temperatures
Frequently Asked Questions
What's a realistic finish time for first-time Comrades Marathon runners?
Most first-time finishers complete the Comrades in 9-11 hours, with 10 hours being a common target. This depends heavily on your preparation level, hill-running experience, and pacing discipline. Conservative early pacing, strategic walking on climbs, and optimized fueling are key to staying well under the 12-hour cutoff. Training specifically for the 89km distance and 1400m elevation gain is non-negotiable for sub-10 hour finishes.
How do I train for Comrades Marathon when my local terrain is flat?
Use hill repeats on any available elevation, even small inclines repeated multiple times. Treadmill incline training (8-10% grade) can build strength effectively. Virtual training platforms and gym simulations help. More importantly, add back-to-back long runs and focus on sustained 4-5 hour efforts at race pace to build aerobic capacity and mental toughness. When possible, travel to hillier terrain for key training blocks in the 8-10 weeks before race day.
Should I walk portions of the Comrades Marathon?
Yes, strategic walking is not failure—it's race intelligence. Elite ultrarunners walk hills or portions of climbs to preserve leg power and mental energy. Walking early saves sprinting power for later phases when other runners are fading. The key is walking with purpose: controlled effort, even pacing, forward momentum. Never shuffle aimlessly. Most sub-9 hour runners walk some sections; many successful finishers walk more. Train your walk pace to be efficient so walking costs minimal time.
What should I eat and drink during the Comrades Marathon?
Aim for 250-300 calories per hour with 500-750ml fluid intake. Use aid stations for solid food (energy bars, peanut butter sandwiches, fruit), sports drinks, and water. Practice your fueling strategy on long training runs before race day. Many runners use electrolyte drinks for first 5-6 hours, then transition to more solid calories in mid-race aid stations. Your gut's ability to process calories over 10+ hours is trainable—this is a critical skill for ultra distance. Never experiment on race day.
How much elevation training is needed for Comrades Marathon preparation?
Aim for 2-3 hill workouts weekly during strength and long-run phases. Include one long run with significant hill content, one dedicated hill-repeat session, and one tempo run on rolling terrain. Progressive weekly elevation gain in training should reach 15,000-20,000m total across your program. The five major hills of the Comrades course demand specific mental and physiological adaptation that only hill-specific training builds. If you lack local elevation, treadmill work and back-to-back long runs on undulating terrain are acceptable alternatives.
What's the best pacing strategy for the Comrades Marathon?
Start conservatively 10-15% slower than goal race pace for the first 25km. This avoids early surging and energy depletion. Middle section (25-65km) should be steady race-pace effort, with strategic walking on hills to preserve power. Final 15km should accelerate only if you have time cushion and energy surplus; if time is tight, maintain steady pace for mental confidence. Break the race into five segments based on the major hills: each becomes a mini-race mentally. Regular pace checks against your cutoff time every 5km keeps you honest and allows early adjustments.
How do I manage the mental challenge of running 89km?
The mental game separates finishers from DNFs. Create a detailed race plan with split targets and contingencies. Develop mantras for low points (typically 60-75km). Use aid stations as mental resets—stand, breathe, reset your mind. Practice visualization in training: imagine hills, imagine fatigue, imagine overcoming it. Break the race into smaller segments—don't think about 89km, think about the next 10km. On race day, embrace discomfort as a sign you're pushing hard. Recognize that everyone is suffering; the winner is who manages it best. Consider having a training partner or friend meet you at strategic points for motivation.
Do I need a pacer or crew for Comrades Marathon?
A crew is helpful but not required for Comrades Marathon. Check current Comrades.com rules for crew access at specific locations. A pacer for the final 20-30km can provide enormous mental and strategic support when you're fatigued. Even without official crew, having a friend at specific aid stations (pre-arranged) provides motivation and can ensure you eat and drink properly when decision-making is compromised. At minimum, train friends or family on what you need at aid stations and secure their support for key points. Solo finishes are absolutely possible with proper self-management.
