I spoke to Mark Beaumont earlier who is on an amazing voyage cycling across the Americas. He has left his bike at the foot of Mount Mckinley and is climbing that now.
I spoke to him this morning and there were a few technical problems, which is understandable as he was 14,000ft up a mountain!
He sounded a little out of breath, which again, is understandable but is doing really well and must be seeing some superb sights.
Keep up to date with his progress here.
