A Walk in The Woods: 2017 Edition of Wendover Woods 50

After having watched the second half of the film adaptation of Bill Bryson’s A Walk in The Woods, I can’t help but spot the remote similarities: an ambitious challenge, an uncompleted journey through the “woods”, and a literary attempt to explain the adventure. In my case, I gave up during a footrace of 50 miles and about 3000 m elevation gain, known in the runner’s world as Wendover Woods 50.

North of the Arctic Circle: Hiking adventures in Sweden

My dream of returning to Northern Sweden for some hiking came true this year. Streams and lakes, puddles and pools, snow and ice, mountains and valleys; orienteering, pathfinding, river crossing, wild camping. Fabulous views rewarded the efforts I put in.

Running the XNRG South Downs Devil's Challenge 2017

It’s bank holiday weekend in the UK. What better thing to do than joining a bunch of nutters for a three-day foot race from Winchester to Eastbourne, covering 156 kilometers and many hills? I could not come up with a better idea, so here is how it went.

Garden of England: Running from Ashford to Canterbury

This Saturday, I decided to explore the North Downs Way between Wye and Canterbury. A trip report touching many things: navigating with phone and compass instead of maps, public footpaths and plough teeth, explosives and barbed wire, parking lots in unexpected places, and oceans of bluebells.

Three Years in the United Kingdom: Need Candles in the Dark

Exactly three years after my arrival in London, the UK Government has triggered article 50. The Brexit drama continues, with decision-making in the dark being a defining part of the play. It is time for a few personal reflections from a “first-row seat”.

Country to Capital 2017: Resurrection

The annual Country to Capital race takes a few hundred enthusiasts from Wendover to London Paddington in what is said to be the opener of the ultra marathon season. There are stark contrasts between country and capital, and it was interesting to observe the gradual transition.

Utility theory and pedestrian behaviour in London

A not-so-serious attempt at explaining pedestrian behaviour in London using utility theory. Ever wondered why certain pedestrians jump so readily in front of passing lorries? Ever wonder why some are keen to collide with approaching cyclists? Sorry, I don’t have the answer, either. But I am still curious. And in a mood to rant. Just a little bit.

How data can assist us in forming good habits

Habits are an important key to success. But how do we establish a habit? How do we know whether our perception aligns with reality? How do we decide about the next change to make? Did we succeed? I want to know. A reflection on habits, insights from data using running as an example.

Wendover Woods 50: First Ultramarathon

November. Saturday. Dark, foggy, chilly. These were the conditions for around 200 loopy runners to set off on a loopy five-lap course through the small, pretty & hilly Wendover Woods. 50 miles later, and after arduous 3000m of ascent, I got a fairly thorough taster lesson in ultrarunning.

Missing Maps: Putting People on the Map

There are places on our planet where people live but there is no map. How are NGOs like Médecins Sans Frontières (MSF) supposed to do field work if they don’t know where people live, how many, how to get there? The Missing Maps project is addressing the issue via crowdsourcing. I gave it a try, and here’s what I think.

Without Captain, Course, Destination: Sailing Away

Several months ago, I concluded a post about the EU referendum with “Sail away. A thought abroad”. I am thoroughly disappointed that the UK actually did. Or half of it? The ship has left the harbour, without captain, without course, without destination, and most disturbingly with a deeply divided crew.
