Just finished my first half marathon. Couldn't be happier!

I've been running seriously for several months and this morning I decided to go for my usual 15k long run. I didn't plan to go any further but by the end of the 15k, I still felt incredible so i decided to go all the way to 21k. I tried to push myself to finish below 1:30 hours, but the lack of good planning and the sudden urge to go to toilet meant that I had to be satisfied with 1:40 hours. Still, it was a good run and i wanna do this more often (once a month maybe), until i find an event that i can enter. Keep running runnit!
