Borneo!

Just a quickie I'm afraid as I'm on a hostel computer and there's a queue.

Have spent the last three weeks in Borneo, travelling around Sabah and Sarawak, and completing two pretty hardcore trekking challenges whilst here.

The first was Mount Kinabalu - the highest peak in South East Asia at 4095m. Not all that high compared to Killimanjaro or Base Camp, but a really tough trek because the first day you ascend 1300m in just 6 or 8km (depending which trail you take), and then the second day you ascend 800m before sunrise, and then have to come all the way down again!

The steps up were far steeper than anything on the way up to Everest Base Camp, and adding to the difficulty is the humidity - sweat literally gushed off my fringe the whole way up.

I made it to Laban Rata - the overnight stop at 3300m in just under 6 hours, and then the next morning it took me a further 2 hrs up, and 1 then 3 hrs back down again.

Accompanying me were Challengers Charlie, Kathy, Denzil, Jesse and Chris.

The second climb was The Pinnacles, a unique rock formation in the Mulu National Park in Sarawak. I thought that Mt K was hard - the Pinnacles Climb seemed twice as steep!

Just wait to watch the video to see how crazily steep the whole 2.4km climb up to the viewpoint was. I think we ascended 1300m again, but in less than half the distance!

Up Mt K every half kilometre is marked - something I'd never seen before up a mountain, though you realise why the markers are needed once you start walking - it's just like a marathon!

And yet up the Pinnacles every 100m is marked! And you feel like it takes you just as long between markers.

Jesse, Denzil and Charlie all also accompanied me up the Pinnacles, so they are all eligible for both Challenge 4 and Challenge 5 t-shirts!

Bring on Challenge 6 - Soweto!
