It was a quite a challenging course for me. I was trying to beat my record time so I tried to keep my pace from the very beginning under-estimate the ascents during the course. I think I burned a lot of my energy during the ascent heading to the Barcelona stadium. Barcelona city has a lot of up and downs and you need to plan your energy resource accordingly. The city without question is beautiful and you have a lot of monuments and scene which can make encourage your endeavor. Overall, it was another great experience in a great city.
