After starting off last Saturday morning at 6:01 from Malin Head in Donegal, Mimi Anderson arrived in Mizen Head in West Cork at 9:37pm on Tuesday evening. That is a new record of 3 days, 15 hours, 36 mins and 23 seconds for running the length of Ireland. The previous record was held by Sharon Gayter when she ran from Malin to Mizen back in March 2012 in 4 days 1 hour 39 minutes and 55 seconds.
Over a year of planning and preparation has gone into this new attempt and now the relevant proof will need to be submitted to make it an official Guinness World Record.
Mimi Anderson has the current record for the fastest time by a female for running from John O’Groats to Lands End in the UK (840 miles in 12 days, 15 hours, 46 minutes). She is also the record holder for the furthest distance covered on a treadmill in 7 days by a female (403.81 miles).
