Individuals who take part have the chance to win a pair of new Reebok ZPump Fusion, given that they reach the finish line.
To get involved in the virtual run, users are first required to find the Reebok Pump logo that is hidden within one of the images in the photo grid on the @zpump_startingline Instagram account.
By liking the photo and tapping on the logo, the user is led to the next Instagram account where another logo is hidden. The virtual run continues in this way, passing through several of San Francisco's landmarks.
Once all of the Reebok Pump logos have been found and liked the user reaches the finish line, where they can enter the prize draw.
Yan Martin, vice president of global brand communications at Reebok said: "Hunt For The Pump is an original and creative way for Reebok to use Instagram to reward the running community and have some fun with the platform.
"San Francisco is one of the greatest running cities in the world and Hunt For The Pump showcases some great landmarks featured in the images. I think people are going to get a real kick out of it and look forward to seeing how successful it can be."
The virtual run will continue until 11 May.
