The TCS New York City Marathon, a 26.2-mile point-to-point race from Staten Island over the Verrazzano-Narrows Bridge to Central Park, offers large aerobic benefits at the cost of heavy training and real injury risk. For health-focused runners, smaller weekly exercise totals deliver much of the benefit with less effort and less risk.
According to New York Road Runners in its race press release, the nonprofit produces the five-borough race. The 2025 race drew more than 50,000 runners from nearly 150 countries and over two million spectators, according to a Cititour guide based on NYRR information. That scale makes training and race day exciting but also crowded and hard to pace.

What health benefits does marathon training add?
Marathon training far exceeds federal aerobic targets. The CDC points to at least 150 minutes per week of moderate activity or 75 minutes per week of vigorous activity for substantial heart, metabolic and mental-health benefits in federal activity guidelines. Inactive adults gain the most from moving toward those targets.
A runner already meeting them gets smaller added health returns from marathon volume. The comparison is therefore uneven. Regular brisk walking, jogging and cycling build fitness with lower fatigue and time cost. Marathon preparation adds endurance and race experience, not a different category of health protection.
How demanding is NYC compared with flatter races?
NYC is demanding and relatively slow. According to Outside in its course breakdown, the course has about 810 feet of gain and 824 feet of loss, with climbs on Verrazzano-Narrows, Queensboro and Central Park hills at miles 23-24. Those late hills punish runners who start too fast.
Bridges add wind exposure and camber stress. Central Park rolling terrain leaves little room to recover before the finish. Typical preparation takes 12 to 16 weeks of progressive long runs, according to Hospital for Special Surgery researchers. Their work found first-time marathoners averaging four or more runs per week had higher injury risk than those running less often.
How high is the injury risk?
Risk is common, not rare. In a randomized study of 720 NYC Marathon runners, Hospital for Special Surgery investigators reported in the peer-reviewed trial report that 8.9 percent had major injuries that impaired training or racing and 48.5 percent had minor injuries. About 7 percent failed to start or finish because of overuse injury.
That means preparation itself can end the goal. Minor pain often continues through training rather than resolving quickly. A separate 16-week study of 1,049 first-time NYC runners found 38.4 percent were injured, most often in the foot, knee and hip. Researchers reported muscle, tendon, fascia and bursa problems rising near race day, with only half seeking care.
How can you lower risk while preparing?
Gradual progression matters more than added strength work alone. In the same NYC trial program, Hospital for Special Surgery researchers found a supervised strength program did not reduce overuse noncompletion, at 7.1 percent versus 7.3 percent.
Longer longest-training runs and avoiding sharp weekly-mileage spikes were linked with lower risk. In practice, that means extend the long run in small steps and hold volume steady after harder weeks. Protect sleep, fuel adequately and treat lingering foot, knee, hip or tendon pain early rather than running through it.
