Mountain biking Snowdon

Last weekend (30 October 2010), we biked up Snowdon.

We’d been planning it for a while, and used facebook to organise the trip – it turned out to be 9 of us, so we booked and stayed at the Eagles bunkhouse in penmachno, which is a great place to stay if you’re in the area, and want somewhere cheap to use as a base for whatever outdoor activities you’ve got planned. It’s basically above/in the Eagles pub, so the evenings are usually spent drinking good welsh ale. They don’t serve food at the pub though, so we ate at a pub down the road called the silver fountain (and I can recommend the HUGE gammon steaks).

On the day of the ride, we set off a little later than planned and had a little bit of trouble finding the correct car park, but found it in the end (The rangers’ station car park, near Rhyd-du). It was raining, and it’s pretty difficult, psychologically, to start a ride in the rain, but it soon tailed off and we got our stuff together and set off. We were well kitted up, with waterproofs, lots of layers, food, drink, first aid kits and lots of mobile phones.

We chose to ride the rangers path, as it’s shorter, but harder, and there was likely to be quite a few people on the llanberis pass, many of whom might not appreciate moving out of the way for a bunch of mountain bikers. The first 30 minutes of the ride was steep, but rideable, with only the odd small section where it was necessary to get off and push or climb. Incidentally, I was carrying a cracked rib from a stupid crash in the peak district a week before, and found that out-of-the-saddle climbing hurt quite a bit, so mostly I’d sit and spin up. Further up, the trail essentially turned into a stream, with water up to 6 inches deep, and technical rocks underneath. This was where it turned into real mountain biking, and you could neither let off the power, or lose concentration – really good fun.

At some point, though i forget how far we had come, we got to where the cloud was hanging down, and it was also the point where it was no longer possible to ride. From here on in, it was 90% pushing, lifting, and carrying the bikes up and over the rocks. Those with light xc bikes, or who were particularly strong, could carry their bikes on their backs, but most of us just opted to push and pull our bikes. Slower – but less painful.



After another half hour or so, the wind really picked up, and it was possible to see the clouds whipping through the valley at incredible speed. Shortly after that, we had rain, and shortly after that, hail. The hail was the worst – strong, bitter wind at 90 degrees to the trail, flinging hailstones hard at you, while you’re struggling to push the bike just a few feet up some rocks. In terms of pure difficulty, it was some of the hardest “biking” I’ve ever done, and there were times when we would just look at each other with a kind of “What the hell are we doing?!” look on our faces.

With visibility terribly poor – between 20 feet and 50 feet, depending on the thickness of the cloud at the time, we never really knew how far we’d come, or how far we’d have to go, but when we reached the train line, we knew we were nearly there, and it also levelled out a bit, with a few sections actually rideable. It was much busier here though, so it was slower going, having to pass a lot of walkers on their way to the summit. We got quite a few funny looks, and lost count of the number of times people asked “You rode your bikes up here?!”

Rather suddenly, we were at the summit, and while it was heaving with walkers, we still managed to get our bikes up onto the triangulation point (we were damned if we were getting our bikes all the way up there and not to the top!), and took some photos. The ascent had taken us just over two hours.

We all then had some sort of hot drink and a bite to eat at the snowdon cafe, added a base layer or two as it was definitely getting colder, and got ready to head back down. As there was a far higher risk of crashes on the descent, we planned to regroup regularly to ensure we didn’t lose anyone (though we nearly lost someone in the first few minutes, due to some confusion about whether they’d seen us head down).



Around 90% of the descent, if not more, is rideable – more so if it’s dry, I’d guess. And with only one or two minor spills, a couple of stops to regroup, it took us not much over 20 minutes to ride down. The trail had definitely collected more water, and we were soaked pretty quickly once we got to the wet sections. It’s a fantastic descent though, and some sections are really fast, while others take a bit more low-speed technical riding. Most of the walkers we passed were very good natured and let us pass easily, though there was a small minority who didn’t appreciate us being there – though I don’t know if they’re aware that bikes are permitted on Snowdon at this time of year.

Sorting ourselves out again at the car park, there was already a lot of talk about which mountain to do next time…

Worldcard mobile iphone app review

Having been to a few shows and conferences recently, and acquiring a number of business cards that inevitably end up loose in my pocket, bag, or on my desk, I decided I’d better have a look for an iphone app that could read and OCR business cards and import the data into my contacts.

So, I downloaded and installed Worldcard mobile from the app store (£3.49), and tried it out.

worldcard mobile

It works pretty well, you fire it up and are presented with a screen where you can choose to photograph a business card, use an existing photo, or use copied text from an email signature (which is a nice addition). Using the taking a photo option then simply gives you a screen with some border edges to get the image straight, and you take the picture. You need fairly decent light for this, and if the business card is laminated, you’ll need to be careful to angle it so you don’t get any glare. If mistakes are made, you can easily correct them in the app itself.

With almost all business cards, it works superbly, reading the text accurately, and placing the data in the correct fields (mobile, email, name, etc). The only issues it seems to have is with particularly colourful and strangely designed business cards. Once you’ve pulled the data out, Worldcard mobile will export it into your contacts, or you can choose to update an existing contact.

Ultimately, a very useful app. The text recognition isn’t perfect, but is good enough in 90% of cases.

Orange vs. Vodafone in Nottingham

The data coverage and bandwidth in Nottingham on Orange has been dismal for quite some time. I actually spoke to them last week about this, and they said that they’re aware of issues in Nottingham, as there are too few 3G masts, and one of them is faulty. They were rather hoping that things would improve once they merged the T-Mobile network into theirs (apparently around the 6th October), though as far as I can tell, it hasn’t.

The photo below shows two speed tests, run on iphones, with the same app, at the same time. The one on the left is on Vodafone, and the one on the right is on orange. You can see the Vodafone download speed is around 3Mbits/sec, which is comparable to ADSL. The Orange speed, on the other hand, is 0.24Mbits/sec; this is around just 6 times faster than a standard dial-up connection.

Total Cost of Ownership – missing benefits?

Total cost of ownership (TCO) is a measure applied to (usually) IT hardware to determine its true cost, and apply that to the cost-benefit analysis. It’s typically used to explain why (for example) a 3-year life cycle for desktop PCs might actually work out a lot less costly than replacing them every 5 years, due to most of the costs being involved in the management and maintenance of the unit itself, rather than the acquisition costs.

The management and maintenance costs usually increase as the hardware ages, partly due to the failure rate, service and support, but also the “cost” of an employee using slow hardware, and the extra time it takes to carry out their work. This cost is really visible when a machine gets so old and slow that the user struggles to operate with it, or the device actually fails. By then, however, the true cost has already exceeded the cost of a new device acquisition, so you’d have been better off replacing it before that point.

What is often missed, however, are the benefits of the new system, as many such benefits are either difficult to measure in financial terms, or they’re simply unknown until the new system is implemented. Of course, if you operate in a very small enterprise, spending too much time calculating the TCO, and attempting to identify the financial benefits of replacement systems could take so long that your time begins to affect the TCO itself, and you’d be better off making very rough estimates. Luckily, it is generally accepted that a 3-4 year lifecycle for desktop machines is appropriate in most cases, and it’s pretty safe to follow that sort of timescale.

Lost at Wharncliffe woods dh trails – steel pendant

Lost pendant at wharncliffe

I was riding at Wharncliffe woods on sunday (26th September), for the first time ever. Some how, even though I only live an hour away, I’d never got around to it. Maybe it’s because most of my mates ride xc, or just that I’m actually quite lazy.The dh trails there are amazing though, and a real credit to the guys at Wharncliffe Riders Collective – technical, rocky, rooty, fast and burly. Proper UK downhill, not like the sterile, manicured trails at most trail centres, but good proper stuff that makes you work for it, and the rewards are all the greater as a result.The downside, however, was that I lost my steel pendant from around my neck (pictured). It was a present from my wife a few years ago, and I’m quite pathetically sentimental about it. I’m not sure which trail I lost it on, as we rode a few different ones, and pushed up a few different routes too. If anyone finds it, I’ll find something to give you in return – beer / wine / bike parts / good karmaLost pendant at wharncliffe / cuddles (everyone like cuddles).Email me at tom.geraghty@yahoo.co.uk or tweet me @tom_geraghty

“Unlimited” data tariffs: What’s a true fair use limit?

Unlimited mobile data

I’m with Orange for my mobile contract, and data hiccups notwithstanding, quite satisfied. When I signed up, however, I asked for their “unlimited” data tariff, which (at the time) I was told had a 500MB “fair use” limit. 500MB? Really? If 500MB is fair use, then what’s standard usage? Do Orange expect people to use less than a couple hundred MB per month? I asked them what they could do to increase the limit, and was told I could bolt on another 500MB for an extra tenner, but I (rightly) guessed that probably wouldn’t be enough either.
As it turns out, they’re able to bolt on one of the low-end datastick tariffs, which turns out as £9 for 10GB per month. Since then, I’ve been merrily downloading and munching on data without any fear of incurring extra fees.
I don’t believe that I’m a particularly heavy user – I listen to podcasts, a little bit of internet radio, use twitter a lot, a bit of web, a bit of facebook, various web apps, and a little video too. Yet, I consistently go over 1GB per month, and sometimes 2GB. If I’m using this, there must be a considerable number of people using significantly more.
What sort of data volumes do you reach per month? And what do you think would be a true “fair use” limit?

Mountain Bike Erosion and Trail Use Study

My dissertation from my degree at Nottingham Trent University, studying the erosional effects of mountain biking, walking, and horse riding on different trails. The study also looked at the social interactions between the different groups of people using the park.

SOLD!: 2006 Specialized Enduro with upgrades and experience!

specialized enduro mtb

After just less than 4 years riding this little beast, I’m selling it. I’ve bought myself a beautiful new Trek Scratch Air 8 to replace it, and hopefully do the Megavalanche in 2011.

This is a 2006 Specialized Enduro (http://www.specialized.com/zz/en/bc/SBCBkModel.jsp?spid=21639&menuItemId=0) but most of the original components have been replaced. The only stock components left are the frame, rear wheel, rear mech, front mech, shifters, seat and seat post.
Over its life, I’ve upgraded to a Fox DHX air 5.0, Marzocchi Bomber 55s, Avid Juicy Seven brakes with 203mm rotors, Sun Double Track front wheel with Reverse 20mm bolt through hub, DMR Wing bars, Race Face b/b, Gravity crankset with bashguard, odi lock-on grips, and DMR V8 pedals.



Before you read any further, you should know that the forks are essentially broken – the lockout has blown and the rebound damping is shot, so they’re pretty uncontrolled. Still rideable, but it’s necessary to replace them. The forks failed at Brechfa a month ago, but I was still able to ride a lot of trails – it was just a little harder to control! The drivetrain is a little worn, but got a fair few miles in it yet. The rear wheel has some pretty serious dings, as you can see in the photos, one ding is right on the seam and has split a little – i have been riding it like that for two years now, so I don’t think it’s too much of a problem. That particular one happened on a dh trail at Ambergate in Derbyshire, where the rocks are really unforgiving. The brake calipers could do with a service, as the pistons don’t return very well, but the brakes are good, and don’t need bleeding. The B/B was new in March this year so should be good for a fair while yet.
The bike’s seen a lot of action, including a few week-long xc trips all over Wales and Scotland (most of the 7 stanes), trips to Cwm Carn downhill course, chicksands, street riding, some xc and dh in Derbyshire and the Peaks, Cannock, and various other trail centres, and even some road miles. I’ve jumped it, dropped it, crashed it, put it in and out of endless car boots and backs of vans, and generally beaten it up. It is covered in scratches, but no dents that I can see, so I assume the frame is still in good condition. It’s capable of fast dh, it’s stable and predictable, and can also climb (just be prepared to work for it). It’s essentially a really good heavy-duty all-rounder, and if you replace the forks and look after it, it’ll be a great bike. If you do replace the forks, I’d suggest you either go for slightly less travel, or the same (160mm), as any longer will make it too slack for general riding.
You can also see in the photos that I’ve ground down the shifters a bit to make them more thumb-friendly when it all gets a bit loose, and there’s a bit of foam in the front mech to keep the crap out.
