Round the island

Well I got to 'the middle of nowhere' fairly comfortably and its 8k to Balik Pilau (BP) from there - mostly downhill / flat.
Once there I thought I'm pretty much half way round the island so after stocking up on water headed toward George Town rather than back the way I'd come.
Pretty soon I regretted that! Wow what a hill going out of BP and it went on and on.
You then have a nice downhill for a couple of k's but then it kicked up again - I had to take a breather before tackling that hill, but once done it was nice riding back home.
I got to Hillside and had to have the dirtiest burger on the menu and then gently pedalled home.
I think it's about 50k but not sure I'll do the map measuring later. (It's 60k)
Wasn't quite at the fitness level to say I enjoyed it!
