If there ever was one of my blogs to read… this is the one. For more reasons than you may expect. I recently received some amazing news: I am one of the winners of the #FocusChallenge. Unfortunately, I also have some bad news. Bad for me and important for you… 


Focus Bikes, a premium bicycle brand from Germany, recently launched #FocusChallenge, a campaign designed to equip ambitious cyclists in the UK with the best possible bike to succeed in their own personal challenge in 2016.

I applied, thinking “you never know” and … am super duper happy to hear I am one of the six winners who will receive one of the award-winning bicycles from Focus to train and participate in my challenge.

My Challenge

As many of you know, I am training to break the solo women’s Land’s End to John o’Groats record. I would have loved to go for the record in 2016, but due to road works on part of the route and time required to get all the logistics organised and put a support crew together, my attempt will have to wait until 2017. However, I will be competing in a number of other challenges and long-distance events during the build-up (including 12-hour and 24-hour time trials and races). It will be great to be able to do so on the new Focus bike.


The challenge is set up in a such a way that whoever of the six winners makes the most noise on social media and creates the best footage and content will ultimately be named the “Challenge Winner”.


So I beg you, whenever you see me posting something on Twitter, Instagram, Facebook, my blog etc with #FocusChallenge, please help me by retweeting, liking, commenting and sharing. The more noise you can help me make, the better.

To have a chance at becoming the Challenge Winner, I need you now more than ever. Why? Because my challenge has just become a little more challenging than expected…

A few days after completing my first solo LEJOG recce ride (over a leisurely 6 days) and receiving this wonderful news about the #FocusChallenge, I suddenly got a cramp in my left calf that just wouldn’t go away. I hadn’t been on the bike for 4 days, so was fairly sure it wasn’t anything muscular. The pain got worse on Tuesday despite more rest. On Wednesday morning I saw my GP and insisted on being referred to the hospital for blood tests. She wanted to just send me home for more rest, but luckily gave in to my request. That afternoon the blood test came up positive for …

Deep Vein Thrombosis

I was given Tinzaparin (heparin), a blood thinner I had to inject myself with over the next 3 days to avoid the risk of the blood clot dislodging and causing a pulmonary embolism (which could be life threatening).

On Friday an ultrasound scan at the hospital confirmed that there was indeed a blood clot in my popliteal vein (at the top of my calf behind the knee). I was prescribed further blood thinning medication (Xarelto aka as Rivaroxaban) and told that I shouldn’t be exercising vigorously and take extreme care when cycling outdoors for a while. The medication thins my blood to a consistency two to three times thinner than usual and if I were to fall off and hurt myself, I could bleed to death as there is no reversal yet. I hope to get some advice from a sports medic with experience of DVT in athletes soon on how/when to safely resume my training and racing.

Friday was my anniversary. Saturday my birthday. I certainly wasn’t in a party mood now and gutted I had to send a DNS to the organiser of the 12-hour time trial on the Sunday I had been looking forward to for so long.

Initially the doctors were baffled (and so was I), because I do not really fit the usual risk profile for Deep Vein Thrombosis (DVT). I don’t smoke, I am not overweight, I am not pregnant, I didn’t just take a long-haul flight. I did not show any obvious symptoms, other than the pain in my calf which seemed to get worse despite rest. My calf wasn’t swollen, red or warm. Both calves measured the same size. I wasn’t short of breath or anything. I looked young, fit and healthy. Why was I wasting their time? But the scan eventually confirmed my fears.

How on earth did I end up from cycling the length of the UK on my own in 6 days one week, to being diagnosed with DVT the next?!

DVT and Athletes

On hind-sight I did actually tick some of the risk factor boxes:

  • I take the anti-conception pill (not anymore now that is for sure!)
  • I have an active lifestyle, but also sit down long-hours for work (something that needs to change!)
  • After my LEJOG recce in the sun and puking a lot due to food poisoning, I probably was quite dehydrated.
  • I then sat on trains all day Friday (travelling down south), behind my laptop all day Saturday (trying to catch up with work), in a car all day Sunday (travelling home), followed by a long night at my desk to prepare for an all-day work meeting the next day and more sitting down on Monday.

These risk factors are probably what provoked the DVT. Although it very much feels as bad luck, I should actually be grateful for catching it so early. Most athletes push through pain and ignore or aren’t fully aware of the risk or the symptoms until they have a full-blown pulmonary embolism. Some aren’t even lucky enough to survive …

Dear fellow athletes, whatever you do, always stay on top of your hydration before, during and after training/races; avoid long periods of sitting down; and take the very first niggles serious. You know your own body. If it doesn’t feel right, there is a good chance something is indeed amiss.


At the moment, I am feeling depressed and sad. I hope to be able to resume my training soon (at least indoors) and get fit and strong to still complete some of my planned challenges for 2016.

Looking at things in a different light, dealing with this DVT setback and hopefully coming back strong(er) from it, should only increase my mental toughness for my epic solo LEJOG record attempt in 2017. That’s what I tell myself on days with my positive-thinking cap on. Other days, I can just think about how much this DVT sucks!

I am trying to focus on what I can do at the moment:

  • Taking steps to avoid a DVT in future
  • Talking to other cyclists who have had DVT and learning from their experiences
  • Getting advice on how to safely resume training and racing
  • Catching up and doing social stuff I would otherwise neglect during the cycling season;
  • Preparing more of the logistics for my LEJOG record attempt next year (e.g. route adjustments, nutrition, light/Garmin/charger solutions etc)
  • Continuing to shout about my record attempt on social media (apologies! but it helps me to stay positive and become even more committed and determined).


I probably won’t be able to fill your social media with exciting images of me riding the new Focus Izalco Chrono on inspiring long-distance challenges in far-flung parts of the country over the next few weeks. Instead there might be stuff of me doing yet another turbo session or trying to strengthen my core… Perhaps there will be footage of me racing as soon as the National 24 hour again. Perhaps even setting a new individual or team record in the process. Who knows?!

However exciting or dull the content may be, if I can please beg you once again, to retweet, like, comment and share anything I post that mentions #FocusChallenge. I am still 100% up for the challenge but, now that the challenge just got a bit more challenging, I need your support more than ever!

Oh and if you could be so kind to share this blog post about DVT. If it raises awareness among others, then at least my current DVT frustrations have had some positive effect too.

Be safe and happy cycling to you all.

    Jasmijn, I had a DVT back in 2012 and 2 weeks after my 6 months of Warfarin finished I had another DVT and am now on Warfarin for life. Throughout the whole period of the DVTs I was very fit and healthy and there has been no explanation for the cause. I found it impossible to get good medical advice and found GP’s to be very poorly informed on DVT and exactly what the medication does and the impact it has. I would advice getting to see a haematologist as everyone else caused confusion and contradiction.

    I have been offered Rivaroxaban but declined as there is no reversal agent and with the extra risks of cycling I wasn’t comfortable with that. Warfarin gets a lot of bad press but is a very well established drug that medics have extensive experience with and it has a reversal mechanism. The testing that comes with Warfarin needn’t be a hassle as you can self test. Check out coaguchek.

    As far as exercising after the DVT again I couldn’t get any proper advice. I just listened to my body and took it easy, slowly building it up. If you have no swelling I’d say just resume train and respond to any pain. My second one had no external symptoms and I continued training with no break. The key is that you are on the medication, keeping active and not stationary and are hydrated.

    Hope it all goes well.

    1. Hi James – sorry for not replying sooner. Do you want to drop me an email (see contact section for address). I have a question to ask you.

    Hi Jasmijn, sorry to hear the news. I had DVT back in 2002 and like you extremely fit at the time. Mine was quite frightening when I think back as I had been having the odd twing in my leg throughout the summer but as I was racing/training hard thought it was due to that, no swelling, cramp or redness. In October I had severe cramp in my calf which after 2 days went to Drs and straight away diagnosed with DVT. On scan found that the pain was from a 2nd DVT as I already had a blockage from mid calf to mid thigh. According to dr as my vascular system was so good (many years doing lots of miles!) my body had just bypassed the initial DVT with very little symptoms. Cue heparin and a year on Warfarin.

    Like you Drs were very puzzled as to why I would get one being so fit, however on a lot of my own research it probably came about by getting dehydrated at events, then spending 1-2 hrs in car driving home and I was also driving a lot for my job at the time. I had very little advice about how much riding/training I could do afterwards other than keep active. Long term for me, my deep vein is totally blocked now so shallower ones have taken over, I still get aches etc in the leg due to post-thrombotic syndrome. Always now make sure I get away from my desk at work on an hourly basis/break up long car journeys etc. I have to admit that I still don’t always drink enough.

    Sorry for such a long post, hopefully as you caught yours early, you won’t have any long term effects. As you know I’m still racing but not riding/training anywhere near as much as I was doing 2000-2003. Six months after mine was diagnosed and whilst still on warfarin I was back racing probably at the not much off the same level.

    1. Hi Neil – don’t apologise. The long reply is much appreciated. Good to share stuff like this. I caught it early so hopefully no long term impact. If anything, you story and those from others who have contacted me about their DVT experiences have actually given me hope and confidence that I should be able to enjoy my cycling soon again and even remain competitive once I resume racing. Important lessons learned on work/life balance, looking after my health and keeping my legs moving. I can see drinking enough can take some discipline, but it gives me a reason to get up from my desk more regularly too. Thanks for sharing and hopefully we will be sharing the roads again soon.

        Hi Jasmijn, glad to be of reassurance. I definitely had a lack of information about how best to proceed after mine, could I still train and race, how hard could I ride etc. it took a while to come up with possible causes and the key one as mentioned was getting dehydrated at events and then being immobile in car. Later on I also found that a slight injury eg knock or bruise to calf/leg could be enough to cause a slight imperfection that coupled with other factors would cause a clot to form and enlarge. Definitely scary stuff and not something one would think fit and active individuals could suffer from. Hopefully catch up with you on the road at some point soon in the future.

    Hi. I’m a friend of a friend (Evans family) and wondered if you hat consisted a standing desk at least at home if you can’t get one at work.
    All the beat in your recovery, may it be speedy

    1. Thanks for your message and follow Ellen. Much appreciated. Nick Evans indeed recommended a standing desk: a vari desk, he has one too. Plus I am thinking of getting one of these for underneath the desk, lol: http://road.cc/content/tech-news/193445-pedal-your-desk-cycli-trainer-now-kickstarter
