CHICAGO --A Polish man set a Guinness World Record by jumping up thousands of steps at Chicago's Willis Tower on Saturday.
Krystian Herba jumped a total of 3,461 steps in three hours, climbing to the 66th floor, taking an elevator back down to the bottom before going up 103 floors to the observation deck. Herba had to stay balanced on the bike the whole time, including the elevator.
Herba said his legs started to cramp over the final 30 floors but was glad he was able to push through them.
The previous record was 3339 steps, set by David Garcia of Mexico on April, 30, 2016.
