Poor Fern Britton is feeling the strain after taking part in a seven day charity bike ride.

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!
