Hello I’m Bill Nelems. I am a Thoracic Surgeon, living in Kelowna British Columbia. Some of my friends and family members have founded an organization called the Okanagan Zambia Health Initiative www.okazhi.org Log on to check us out. We support capacity building and educational needs of health care workers in Zambia. Our two focus areas are Lusaka the capital city and all of Western Province. The Tour d’Afrique www.tourdafrique.com began their annual trek from Cairo to Cape Town on January 16, 2010. On April 7, 2010, when they reached Lilongwe, Malawi, Lianne, Jessica and I joined them. We rode to raise funds that will be given exclusively to our organization. We will be paying for our own trip expenses. This blog hopes to catch the events of our trip………… The Tour d'Afrique reached Cape Town on May 15, 2010 completing our journey....

Welcome

Follow us on the Tour d'Afrique. Lilongwe, Malawi to Cape Town, South Africa.

Windhoek to Sesriem and the Dunes, 223 kms in 3 days.

For our first 6 days in Namibia, we saw a daily continuation of the violent electrical storms that we experienced in Botswana. It’s been raining virtually non-stop.
Perhaps my impression of the storms is embellished, because, for the most part, we have only the skins of our tents and our raincoats as our main sources of protection. My tent is soaking wet, my clothes musty and my sleeping bag damp.

We rode three days from Windhoek to Sessriem, with legs of only 115, 125 and 83 kms.
These distances pale by comparison to those done in the last few legs. However, there were some ‘mitigating’ factors about which you are about to learn, that made these days more than a little formidable.

My sister Bev, before I left to join the Tour reassured me about the roads in Namibia.
“Bill, the particular roads that you will be travelling on in Namibia are all gravel from Windhoek to the South African border. But you don’t have to worry – they’re the best gravel roads in the world.”
Perhaps roads look different from the seat of a bicycle compared to those seen from the comfort of an air-conditioned expedition vehicle.
Bev could have said, “…gravel and sand.” But she didn’t. She left it for me to discover the sand.
Sand – the kind of sand that takes 10 kph off your average ground level speed.
Sand – the kind of sand that makes climbing hills much more difficult.
Sand – the kind of sand that makes you moderate your downhill speed. If you don’t slow down – you will skid and crash. Four riders spilled on the downhills. One separated a rib cartilage and another bent her front wheel rim.
Sand – the kind of sand that makes your upper body struggle and strain to keep the front wheel from twisting.
Sand – you know – the kind of sand that this mornings rain has turned to mud.

And then there are the road corrugations. I know all about corrugations, but my memory of them was embedded in some dormant part of my brain. Within the first metre of hitting the gravel road, I remembered the corrugations, recalling past encounters.
Think about it – all gravel roads are corrugated - three corrugations per metre.
OK – grandchildren – Kate, Lucy, Willem and Ander – it’s time a mathematics test……….
If there are 3 corrugations in every metre of ground travelled, and if there are 1000 metres per kilometre, how many corrugations are there in 1 kilometre?
Mmmm – let’s see? 3 x 1000 = 3000. You’re right. That’s how many corrugations you hit each kilometre. That’s how often your shoulders get jarred – not to mention the bum hits!
Some days you have choices to make – ride the thick sand next to the car ruts or ride the corrugations.
CornĂ©, riding the corrugations is a little like horse riding. If you are slow, it’s like trotting. Every corrugation sends a jarring jolt up your spine. But if you can increase the speed a bit, it is a little like cantering. It’s less bumpy as you round off the tops of the ridges, but it’s difficult to maintain. That, however, is where the comparison ends. When you ride a horse, the horse does most of the work. When you ride a bike, you do all the work!

The 115 km ride from Windhoek to our first southern bush-camp took me as long to ride as did my now famous 207 forays done on my 71st birthday.
First, it took me two hours to climb the first 24 kms into the hills south of Windhoek. Looking back, it’s a beautiful city embedded in mountains and valleys. We had headwinds coming into Windhoek and we had headwinds leaving. It doesn’t get its name for no reason. ‘Windhoek’ translated means ‘windy corner’!
Next, once up in the plateau, and for a considerable time, I could not get my speed up above 5 kph, what with the sand, the mud and the headwinds.
Then began about twenty ‘rolling hills’ before camp.
‘Rolling hills’ are synonymous with zero net elevation gain or loss. One rides up one hill, down the next valley only to repeat this zero gain game over and over. Whilst there is no gain or loss of altitude, there is a gradual and progressive drain in the body’s energy systems.
Remember, climbing the hills makes you strong, and riding the flat makes you fit!
On our second day south of Windhoek, as I climbed Spreetshoogte Pass, I thought of you Michael.
“Bill, you can’t lift a 1000 pound weight, but you can lift a one pound weight 1000 times. It’s like that when riding the hills.”
So, as I geared down to my lowest gear and grinded it out, your advice brought me comfort. By the way, tell Maria that I’m loading up on carbs theses days!
Reaching the bottom of the Pass, we faced headwinds all the way to camp – headwinds, rain and mud – and throw in a few rolling hills for good measure. For about 40 minutes I was caught up on the edge of one of these monster storms. Rolling claps of thunder and torrents of rain followed each bolt of lightning. It was one of my most difficult days.
I witnessed a most remarkable display of both horizontal sheet lighting strikes as well as the more common vertical ground strikes.
Sheet lightening happens when one cloud discharges its electrical current into an adjacent less charged cloud. Ground lightening happens when a cloud’s electricity is discharged to the ground. Sheet lightening endangers aircraft. Ground lightening endangers buildings and humans.
Our third day south of Windhoek, a mere 83 kms, began like so many other recent rides – in another electrical storm!
Sessriem, on the edge of the famous Namibian dunes in the Namib desert, saw the end of the storms as we had known them for the past two weeks, but the ground was moist, the potholes brimming. They had received rain the night before we arrived.

My choice of bicycle proved to be excellent, whereas my choice of tyres was poor. As some of you know, I toyed with the idea of riding a bamboo bike. But we had some major problems with it before I left, and Marty and Jim urged me to take my steel Specialized bike with the 29-inch tyres. It was a good decision.
Jessica and Lianne did ride through Zambia with bamboo bikes. Whilst they completed their rides in good form, they were not without significant challenges.
I took two sets of tyres – a narrow Armadillo set and a broader flat top – lateral lug type.
I took the Armadillo’s for two reasons. They would give me faster speeds on the paved roads of Zambia, Botswana and South Africa. Also, they market this tyre as the toughest on the road.

The problem was that ‘paved’ roads in Africa aren’t always as suspected. The road from Lusaka to Victoria Falls is heavily potholed and there are at least 4 road construction detours. The ‘paved’ roads in Botswana consist, for the most part, of tar impregnated crushed rock. It’s anything but smooth. The Armadillo’s got me about 100 kms into Botswana before being discarded, along with their reputation for toughness, into a refuse bin. They were no match for these roads. The broader tyres fared even worse. They got ditched in Maun, riddled with holes. I borrowed tyres from fellow riders to get me to Windhoek where I got some sturdy all-purpose Namibian tyres. So far, gravel and sand notwithstanding, they are holding up well.
Our day off saw us go for a 5-hour day trip to the famous dunes.
On our safari van were Annalise, investment banker from Australia, Cat the corporate lawyer from New York, Katia, a business consultant from South Africa, Jim, a lawyer from Portland, Oregon, Michael the British Medical Student. His lip is healing beautifully. What a great group of people and what a magnificent day. I know now why photo enthusiasts like Bev rave about Namibia.
Next, we have 5 riding days to Felix Unite on the Namibian – South African border.
Don’t worry folks – we’ll be riding on the best-maintained gravel roads in the world!!!
As Glynn would say, “It’s all good, I’m loving it!”
