"Day 26 - Mile 11 - I'm expecting a good view over the horizon. #eyrehighway #mundrabilla #nullarbor"
"The cliffs to me left give me a feeling of progress. #eyrehighway #mundrabilla #nullarbor #rgrdownunder"
"Painkillers have kicked in. Can't feel a thing in my feet. This is bliss. Going to have to take 4 lots today to get to #eucla."
"Time to raise my game with the #roadtrain drivers. #fistpumps and #salutes for starters."
"Deep in thought today about what I'm going to tell @GaryandLisaReal on Monday's show and how I'm going to say it. It's going to be tough."
"Good progress today thanks to #painkillers. 40km to #eucla #nullarbor #eyrehighway"
11:15 - "15 miles done. Just ducked into the RV. Waiting for a shower to pass over. Not risking getting my feet wet. Don't want more problems."

"Managed to catch up with messages on uk.virginmoneygiving.com/rungeordierun during the last break. Thanks everyone for charity cash and kind messages."

"Getting slightly closer to strange coloured land mass. It's still a long way away"
".. and Mysterious Girl plays on #now57 on the iPod. Could this afternoon BE any better!"
"The land mass in the distance is starting to look like chalky cliffs. These are the same eyes that saw a monkey in dungarees 2 weeks ago."
"It has been very windy this afternoon. That means I haven't seem a single one of Australia's foot soldiers (flies)."
"Meanwhile, in #stobbsytales, #japanesealan told me that @jasonstobbs oriental tattoo translates to "I love Lottie". #true #honest"
"I've been talking to #japanesealan via Facebook today who is still injured and resting in #mundrabilla. He hits the road again tomorrow."
16:35 - "898 miles done so far. (30 today) - day 26"
"Stopping for food at mile 899. Running into the #nullarbor wind is so energy sapping. #eucla is 4.3 miles away."
"Forgot to offer @jasonstobbs one of my M&Ms. He's giving me the evils. #stobbsytales"
"Food break over. Time to smash the 900 mile barrier. #rgrdownunder with @drivebenfield"

"I can see the sea. I can see the sea. I can see the see to my right. I can see the sea!!!"
"Sunset at #eucla @australia #eyrehighway #nullarbor"

"Last bit of light at the top of the hill in #eucla."
"@JasonStobbs tells me the fish and chips in #Eucla are good. I'm getting some! I'm stopping here. 36.5 done."

"It turns out that @jasonstobbs favourite band is #enya. Who knew! #stobbsytales"
