I entered the Lanzarote Ironman in 2008 - I had trained for 10 months for it and I was excited and nervous.
I got to the start line (7am) feeling actually quite calm and excited...I lined up near the back as I was expecting to be quite slow and didn't want to get trampled to death in the rush forward. I got in the water and completed the two loops in 1 hour 23 mins - I was chuffed with that.
I got to the changing area and there was this woman yealling and kicking up a massive fuss for the girls to get her the sun tan lotion - she was creating quite a scene! I looked out and it was completely clouded over - I thought I can either wait here for the lotion or depend on the stuff I had put on myself before we left the apartment...well I went for the second option. (d'urr!!)
So I ran out got on the bike (still more than a third of the bikes were left...again I was pleased with that!) So I head out the road and riders are passing me (I'm dead slow on the bike) and (if anyone knows Lanzarote) the wind picks up and the clouds clear.
To cut a long story short - I ended up at 95 miles with sunstroke and severe sunburn...in my head I was calcluating the distance I had to go and I felt I was going to miss the cutoff...so when I saw the guards I called them over and said that I wasn't going to finish.
It turns out that with the sunstroke I was completely miscalculating the time and the distance - I could have finished inside the cutoff...but as it was I ended up with second degree burns on my face and hands - my ears were so bad that I couldn't lie in bed on my side...it was a nightmare.
(And it was 6 weeks before my daughter's wedding so you can imagine the comedy tan lines I had to deal with!!)
