do a duathlon

I live in Florida. I ran the duathlon during summer time. I was just practicing to see if I would be able to do it. It was a hot and extremely windy because Hurricane Dennis was near. Running was easy but I always go for jogs. When I got on my bike, it felt like a nice break from running but after about the fifth mile, my butt started to hurt. My bike seat was so uncomfortable. When I ran the last 2 miles, I was sore. If you ever do a duathlon, make sure you have a comfortable bike seat. 3 weeks later and I’m still sore.
