Training for a half marathon can be a daunting task on its own, but when you add the challenges of Postural Orthostatic Tachycardia Syndrome (POTS), it introduces a unique set of hurdles. The sudden racing heart, dizziness, and fatigue are symptoms that many with POTS know well, and they can strike unexpectedly during a run — often described as being hit 'with a vengeance.' From my own experience preparing for long-distance events while managing POTS, preparation and mindset are key. In the days leading up to the race, I've found that focusing on hydration, electrolyte balance, and pacing myself helps mitigate some of the intense symptoms. It's crucial to listen to your body and not push beyond your limits, especially if symptoms begin to intensify mid-run. Mental preparation also plays a significant role. Acknowledging the fear and anxiety before the race helps in accepting that not every run will be perfect, but each step counts toward progress. I recommend visualizing the course and planning breaks where possible to regulate heart rate and rest. Another helpful strategy is to communicate with race organizers about your condition beforehand if you feel comfortable. Having support or access to medical personnel aware of your situation can provide peace of mind. Lastly, joining support groups for runners with POTS can offer encouragement and practical advice. Knowing others share similar experiences reduces isolation and builds confidence. Facing a half marathon while dealing with POTS is undeniably challenging, but with careful preparation and self-compassion, it can become an empowering achievement rather than a source of fear.
