Just spoke to Bianca on the radio and they are about about to start their climb to the summit.
The radio quality wasn’t great but she sounded good and is ready to go. It’s still light now so they have about another hour of light and then will be climbing through the night.
Hopefully her tracker works (even though it says Paul, it’s Bianca carrying it). If there are erratic jumps or the tracker stops, don’t panic. They also have a radio with them and will hopefully give updates as they get to milestones. (I’ll update here when I know anything more.)
Keep everything crossed!
