I did it. after 2½ month of BF/VFF running I completed my first VFFhalf-marathon. The goal was to complete the marathon and I took it really slow and I completed in 2 hours and 19 minutes.
That doesn't seem slow to me! Particularly only 2.5 month into the transition. I would have thought it's not enough time to transition to such a distance without risking getting injured. I'm glad it worked for you. Congratulations!
