The second annual Gritty 5K presented by Penn Medicine had a little bit of a different look this year, going completely virtual for participants. Spanning 50 states and 10 different countries, over 2,800 "gritizens" sported their best orange and black costumes to hit the streets and run (or walk) for charity.

Race participants had the option to run five kilometers in their own hometowns at any time between September 17 and 20 while donning their best Gritty costumes. Through an online race platform, runners submitted their time and photos to be eligible for specialty prizes such as "best in fur," "most exotic route," and other surprise awards selected by Gritty himself.
