I signed up for this race because we were on holiday in Lanzarote when it was scheduled.
Turned up to pick up my race number and timing chip on the day before the event to be informed I couldn’t compete unless I underwent a full medical examination. We spent the next 8 hours driving around clinics/medical centres and hospitals trying to get me examined to the required standard. Eventually had examination including ECG, lung capacity, blood pressure, fitness test ( 45 squats in 60 seconds HR taken before during and after, time taken to drop to resting Hr etc,).
Fortunately I passed and was given certificate to race.
Following morning realised what I had signed up for i.e. 42k across lavafields, 3000 plus metres of ascent,very scary descents and temperatures which were 31degrees over last section of race.
My fellow competitors all seemed pretty serious in terms of appearance and kit, racing snakes and Salomon X labs were standard.
Turned into hardest marathon I have ever run. Loved much of it, the challenge and spectacular views from the tops of the 5 volcanic caldera that we climbed. Did not enjoy some of the descents. Fell too many times, lost a lot of skin but gained a number of cactus spines.
Finished 17th out of 90 starters, but won a trophy for the over 50 category.
