It is difficult to immediately realize the dimensions of what the biker Borislav Yordanov did in recent months. He didn't just set a new record on the Com-Emine route. He did it TWICE, in just one summer!

The new cycling record will probably belong to him for quite a long time - under three days, 2 days and 22 hours to be exact. In the toughest section of x. “Dobrila” to Mount Botev alongside him runs the record runner Antonia Grigorova. Both of them will tell us about their motivation, trials and personal formula of success at the 13th Days of Challenges. Together with Borislav on stage we will see another main culprit for the realization of Bicycle ride - organizer Kalin Rusev.
