But no. This was a legit hike up to the first zip. It took me one hour and 15 minutes.''I was so grateful for the support of the guides and my friend @jharris1231 who helped me up, and the other people on the hike that never judged me or made me feel stupid. Thanku.'She added the hashtags '#gratefulforepsomsalts' and '#dontletcancerruinyourday.'Fans flooded Lucy's post with messages, calling her 'an inspiration.'Lucy replied to many of the messages, admitting to one fan that the zipline 'was the easy bit - it was having to walk past bee hives that scared me the most!'
