A runner who completed 30 marathons in as many days is taking on the London Marathon this Sunday - with a 30kg fridge on her back.<br /><br />Laura Bird, 31, has clocked up an incredible more than 300 miles and gone through three pairs of trainers while preparing for and completing races. <br /><br />In 2020, she ran 10 marathons in 10 days in 10 different towns and cities across the UK.<br /><br />In her latest challenge, Laura will be running the 26.2 mile course with a fridge strapped to her back - and aims to complete it in less than 6 hours.<br /><br />Her endeavours have seen her raise £12,550 for East Anglian Air Ambulance after they saved her life in 2010 when she attempted to take her life by jumping in front of a lorry - aged 18. <br /><br />Laura, an environmental consultant, from St Ives, Cambridgeshire, said: "It takes a lot of hard work and a lot of time on your feet just to get the mileage in - with persistent running for four days on the trot and spending a lot of time in the gym.<br /><br />“Psychologically, the 30 day challenge was harder because I had to hold it together and not be injured or ill for a whole month.<br /><br />"But physically the 10 day challenge was certainly more taxing.” <br /><br />This weekend Laura will attempt to break a Guinness World Record by becoming the first woman to run a marathon with a fridge on her back - to raise money for children's charity Rays of Sunshine. <br /><br />The fridge will weigh between 25 to 30kg and will be attached to her back using a military grade harness. <br /><br />“I’ve been training with a fridge on my back for seven months now and it’s without a doubt the hardest thing I’ve ever done," she said.<br /><br />"The first challenge was working out how to even get it on my back, with a company sponsoring me buying a military grade harness for me to use. <br /><br />“Then it literally started with going out for half a mile or a mile just walking to start off with.<br /><br />"But the training has gone really well and it’s attracted quite a lot of attention in the local area which is a good thing because it means people have donated more.” <br /><br />Laura has currently raised £12.5k for Rays of Sunshine and more than £11k for East Anglian Air Ambulance through her ultra-marathon challenges. <br /><br />She credits the air ambulance service with saving her life after she walked out in front of a lorry in 2010 - and was left with life-threatening injuries. <br /><br />Laura said: "My grandad, who we sadly lost in 2020, was also called Ray who got his name from being such a ray of sunshine, he was a lovely man and that really resonated with me when I first saw the charity." <br /><br />Training for events like this relies on a strict diet.<br /><br />Laura said: "It’s naughty but I love a can of coke.<br /><br />"If I’m out and about at 6 in the morning on the weekends I’ll be drinking coke by 7.30am.<br /><br />“I’m hungry all the time. I mainly eat lots of fruit and veg and pasta and the thing that gets most people is I carry a lot of baby food around with me because the pouches can be really handy when training.” <br /><br />Alongside these feats, Laura has appeared in the 2019 se
