VERTIGO is not putting off two Potters Bar mums from trekking across one of the world’s largest mountain ranges.

Despite Janine Harkness’ and Sharon McCarthy’s terrible fear of heights, they are embarking on “the biggest challenge of their life yet” – hiking along the Inca Trail, in Peru, in November.

The mums-of-three- and-two respectively have already started raising funds for Great Ormond Street Hospital with a series of events, including an Easter raffle and cake baking, which has helped to raise more than �1,000 so far.

In total, they hope to donate �5,500 and Janine told the Potters Bar Edition if they are not close soon she will shave her head to get the necessary cash.

Janine said she had chosen to raise money for GOSH because, as a former nurse, she trained to work with children but had to pull out for personal reasons.

She said: “This is my way of making recompense.

“I’ve always wanted to do the Inca Trail, but never got round to doing it.”

The colleagues at Canada Life, on High Street, are already in training for the 10-day challenge, which includes steep drops and narrow passes at high altitude, culminating with a stretch reassuringly named Dead Woman’s Pass.

Janine, from Hatfield Road, added she was most looking forward to the physical challenge itself, as well as embracing the mythical ambience.

As for the heights, well Janine is hoping the trek will help her conquer the fear and the same can be said for Sharon.

“It’s a mental thing that is there from early human to stop us from doing stupid things, so I’m hoping that I will be able to turn it off and get over my fear,” Janine said.

Their next fundraising event is tomorrow (Thursday) at the Strafford Arms, Mutton Lane, where an Elvis impersonator, namely Alvin Printwhistle, will be performing.

They will also be raising cash at the Potters Bar Carnival on Sunday, June 13, and at the community fun day in Oakmere Park on Saturday, July 10.
