In December 2010, tennis legend Martina Navratilova was forced to abandon her Kilimanjaro climb at 14,800 feet. Despite being one of the greatest athletes in history, she was hospitalized with High-Altitude Pulmonary Edema (HAPE). Her story serves as a critical lesson: Mount Kilimanjaro demands respect, regardless of your fitness level.
What is HAPE? HAPE is a life-threatening build-up of fluid in the lungs caused by rapid ascent to high altitudes. Unlike standard altitude sickness (AMS), HAPE prevents oxygen from entering the bloodstream. The only treatment is immediate descent. Navratilova’s symptoms—extreme exhaustion and inability to catch a full breath—are classic “red flags.”

The “Survival” Conditions Navratilova was climbing a 7-day Rongai variation during a period of extreme weather. Sleet, snow, and relentless cold plagued the team. “Nobody had fun. It was just survival,” she recalled. These conditions often mask the early symptoms of HAPE, as climbers mistake fluid in the lungs for a simple cold or physical exhaustion.
“I didn’t feel badly, I just couldn’t breathe. I couldn’t get a full breath of air… Nothing hurt, and for an athlete that’s weird.”

🏔️ Expert Analysis: Fitness vs. Acclimatization
Navratilova’s experience proves a vital point: Physical fitness is not a shield against altitude sickness. High-performance athletes are sometimes more at risk because they are mentally accustomed to “pushing through” discomfort. On Kilimanjaro, pushing through HAPE symptoms can be fatal.
The Importance of Daily Health Checks
Navratilova’s complications began on Day 4 (12,200 ft). At Ultimate Kilimanjaro®, our guides perform twice-daily pulse oximetry tests. Had Navratilova been monitored with these protocols, the early signs of lung fluid may have been caught before she required an emergency evacuation.
Ultimately, 33% of her team failed to summit. Navratilova remains proud of the attempt: “I always said the only failure is when you fail to try… I tried and gave my best effort.”
