A woman who's been planning a trip to Nepal to run the Everest Marathon says she won't cancel her trip.

The 7.8 magnitude earthquake that's rocked the area has caused huge avalanches on the mountain, and taken out parts of Everest Base Camp, where the marathon's supposed to begin.

Lesley Turner-Hall says the last 12-14 hours have made her think twice about the trip... but now she's more focussed than ever.

She says her first thought was that there could be another earthquake while she's over there in a few weeks' time.
