Staff at a leading accountancy firm are totting up the miles as they prepare to take on the challenge of a lifetime.
Tax experts Helen Smith, Stephanie Day and Gemma Talbot, who all work for BDO in Leeds, are in training to climb the 5,895 metres of Kilimanjaro, Africa's highest mountain.
The intrepid trio are taking on the daunting task to raise money for the Jane Tomlinson Appeal and they have set themselves an appropriate target - £5,895.
Helen, 31, a senior tax manager, who lives in Wakefield, said: "A pound for every metre seemed a good idea."
As part of their training to get in shape for the climb, Helen, Stephanie and Gemma will join three BDO colleagues - Dominic Campbell, Krishan Korpal and Laura Chivers - in taking part in the James Potter Eggs Corporate Relay Challenge, which forms part of The Plusnet Yorkshire Marathon on October 20 in York.
Gemma and Helen recently completed the 14 mile route of the Jane Tomlinson Yorkshire Dales Walking Festival. More expeditions to the Dales and to Snowdon in Wales are planned along with a series of 5K and 10K runs ahead of next May's Kilimanjaro challenge. There has even been talk of tackling the national Three Peaks Challenge - Ben Nevis, Scafell Pike and Snowdon.
Tax manager Stephanie, 29, said: "We had read about climbing Kilimanjaro. We spoke to each other about it and we were all up for it. We are extremely nervous but excited as well."
While acknowledging they are not natural runners, the women said they were looking forward to taking on the corporate relay challenge and being part of the first Plusnet Yorkshire Marathon.

The eagerly-awaited marathon sold out of general places within days of being launched, leaving corporate team relay entry as now the only way to be part of the high-profile event on October 20.
Hundreds of businessmen and women from scores of companies will be bidding to be crowned Yorkshire's fastest firm. Legal companies, major manufacturers, architectural practices and banks are among those to have secured their relay places.
The Plusnet Yorkshire Marathon is being staged by a new company under the Jane Tomlinson charity events umbrella - the legacy of the late fundraiser of the same name who raised almost £2m for charity through a series of amazing endurance feats.
