Fern, 55, is currently cycling between Estonia and Russia to help raise money for the Genesis Research Trust, which helps cure life-threatening conditions contracted by women and babies.
An exhasted Fern tweeted a picture (below) of her taking a much needed break during the ride along with the caption: ‘A little snooze after lunch and 70k.’
And we can see why she needed a lie down, over the 7 days Fern and her fellow cyclists are riding up to 110k a day (that’s over 68 miles)!
Fern tweeted yesterday: ‘Day 3 tired legs after 110k yesterday. 60k to Russian border!’
Keep up the good work Fern!
