heart rate question

I m not running in races as I trail run for the love of the trail and to allow myself to hike long distances. I trail run about 60 miles per month. I am 54..My question is: Occasionally, after about 2 to 2.5 miles, especially going up hill, i become light headed and seem to be losing my breath. I have to stop and stand still, then continue on. And then for the remainder of my run, especially up hill i have to deal with this uncomfortableness and stopping and starting back to the trailhead. Again , this doesnt happen to me everytime, just occasionally. Have you ever experienced this or know what is happening to me ?

Hey I think you should talk to a doctor about that one, especially if it's a newer observation for you.

I’ve had similar episodes on steep trails - turned out I wasn’t hydrating enough before the run. Try sipping an electrolyte drink 30 mins prior and see if it helps. That said, intermittent dizziness + breathlessness at 54 is worth mentioning to your doctor, just to rule out anything cardiac. Better safe than sorry!

I’ve had similar experiences on tough uphill sections. For me, it turned out to be a mix of dehydration and pushing myself too hard on the inclines. One thing that helped was making sure I was properly fueled and hydrated before the run, especially with electrolytes. Sometimes taking a short break during those steeper sections also helps me reset and avoid getting lightheaded. Still, if this is something that’s becoming more frequent, it wouldn’t hurt to check in with a doctor, just to be on the safe side.
