Our founder, Cat Woods, ran her first marathon in January 2016, by December that year she'd completed her 12th, raising just short of £2,000 for MIND.
Following the challenge, 12in12.run was formed to prove that with running anything is possible if you put your mind to it.
12in12.run seeks to reward runners who take part in consecutive public events over a distance and duration of their choosing.
It's your challenge. You decide.
