Hi all. I’m new here, and I apologise if my question has been asked and answered. There are so many questions/stories on here!
I completed Oxfam Trailwalker (100km walk/run for those who are not familiar) on Saturday morning after 25 hours on the trail. When I got undressed to have a shower, I had a rash– more like flushing–across my chest. It gradually spread up my neck, to my face, and down my back. It became itchy over the next 24 hours, and now, another 48 hours down the track it has started to settle. There is still some itching, but not enough to take anything for it. The redness has also mostly gone.
I have had this type of reaction following long (20km+) runs in the past, but this has been the worst in terms of the itching. Other info – I don’t experience any symptoms during the period of exertion. I am also quite prone to viral rashes, and I do not sweat heavily.
My doctor believes I have cholinergic urticaria. I think it’s the most likely explanation, but I would like to know if others have the same symptoms, as I keep reading that the reaction usually subsides quite quickly. I am particularly interested in hearing from people who participate in endurance events, and how you manage it, as I don’t intend to stop running!
