Always seek personalised medical advice before starting any new recovery therapy, particularly if you have a pre-existing cardiovascular, respiratory, circulatory, or musculoskeletal condition, or are pregnant. Cryo SubZero staff will conduct a health screening prior to your first session.
Recovery after a marathon varies between runners. Prioritise sleep, nutrition, hydration and a gradual return to activity. Additional recovery modalities are optional, and evidence for their effects is mixed; no single therapy has been established as best for everyone.
What a Marathon Actually Does to Your Body
Running 42.2 kilometres, especially with the repeated eccentric loading of every footstrike, causes measurable exercise-inducedmuscle damage (EIMD). Creatine kinase rises, inflammatory markers climb, muscle fibres develop microscopic tears, and glycogen stores are close to empty. This triggers the inflammatory cascade responsible for delayed onset muscle soreness (DOMS), which typically peaks 24 to 72 hours post-race and can leave muscle function and jump performance depressed for several days. Recovery is essentially a race between damage clearance, inflammation resolution, and rebuilding, and every recovery modality is trying to influence one of those three levers.
Cold water immersion is the most studied post-marathon recovery tool, and the results are genuinely mixed rather than glowing. A large network meta-analysis pooling 55 randomised controlled trials found that lower temperatures and longer durations of immersion produced better reductions in soreness and creatine kinase than shorter, warmer protocols, but the effect sizes were modest 1 . A dedicated post-marathon trial found that combining cold water immersion with tart cherry juice offered no advantage over either intervention alone, and none of the three approaches produced statistically significant improvements over placebo in inflammatory markers 2. Repeated daily immersions across 72 hours did reduce muscle thickness and swelling more than passive rest, without changing systemic inflammation 3. The honest summary: cold water immersion reliably reduces the feeling ofsoreness, but its effect on actual muscle damage markers is smaller than most runners assume.
Whole-Body Cryotherapy
Studies of whole-body cryotherapy after running have reported mixed findings. Changes in soreness or blood markers do not necessarily mean faster functional recovery, and results from one protocol should not be assumed to apply to another. Cryotherapy is an optional wellness modality with uncertain post-marathon benefits; sleep, nutrition, hydration and graded activity remain the priorities.
💆✨ Massage
Massage has one of the more consistent evidence bases of any recovery modality. A meta-analysis of 11 randomised controlled trials covering 504 participants found massage significantly reduced muscle soreness at 24, 48 and 72 hours post-exercise, improved measures of muscle strength and peak torque, and lowered creatine kinase compared to no intervention. Interestingly, the soreness-reducing effect was strongest when massage was delivered 48 to 72 hours after exercise rather than immediately, suggesting the day-two or day-three window matters more than getting on the table straight after the race.
🧦 Compression Garments
Compression tights and calf sleeves have a moderate evidence base. Meta-analyses have found compression garments produce small but statistically significant improvements in the recovery of muscle strength and power after fatiguing exercise, with the strongest effects seen when garments are worn for extended periods post-exercise rather than briefly. Effects on soreness and swelling are generally more reliable than effects on actual performance metrics, and the benefit appears to depend heavily on pressure and fit, which most off-the-shelf garments do not standardise well.
😴 Sleep
Sleep is the recovery tool almost nobody treats as a therapy, and it may be the most important one. Controlled research restricting sleep to four hours a night for five nights found myofibrillar protein synthesis dropped by roughly 18 to 19 percent compared to normal sleep, and a single night of total sleep deprivation has been shown to measurably suppress muscle protein synthesis pathways in humans10. If you run a marathon and then get a poor night's sleep to "make up for lost time," you are actively working against the repair process your body needs most.
Who Should Be Cautious
| Modality | Caution or contraindication |
|---|---|
| Cold water immersion / cryotherapy | Cardiovascular disease, uncontrolled hypertension, Raynaud's phenomenon, cold urticaria, pregnancy, open wounds |
| Compression garments | Peripheral arterial disease, active DVT or clotting disorders |
| HBOT | Untreated pneumothorax, certain ear/sinus conditions, some chemotherapy agents |
| Massage | Acute DVT, unhealed fractures, some skin infections |
None of these are reasons to avoid recovery therapy altogether. They're reasons to have a real conversation with the practitioner beforehand rather than assuming every modality suits every body.
What Elite and Recreational Marathoners Actually Do
Athletes use a range of recovery habits, but popularity does not establish effectiveness. Sleep, nutrition, hydration and a gradual return to activity should guide recovery. Massage, compression and cold exposure are optional; effects vary and do not establish a universally superior approach.
How Cryo SubZero Approaches Marathon Recovery
Cryo SubZero offers optional wellness sessions alongside the basics of recovery: sleep, nutrition, hydration and graded activity. Evidence does not establish our modalities, individually or combined, as the best way to recover after a marathon. Our team can explain session options and suitability screening. Persistent pain or suspected injury should be assessed by a qualified healthcare professional.
