Ricardo Abad Martínez (Tafalla, January 8, 1971) is a Spanish ultrarunner.
Abad sold each of the 21,000 km he ran at the rate of one euro each and donated the money to ANFAS, a Spanish organization that works in favour of people with intellectual disabilities.
Ricardo broke the world record for consecutive marathons (366) on 1 October 2011 in Madrid.
He set May 22, 2012 as the deadline to find the necessary funding for the project, which included running a marathon in every continent in the world.
Finally, after failing to find financing, he abandoned the project on 29 May 2012 after 607 marathons, which is the current world record.
