Blimey - it's amazing that you're still around and finding intriguing ways of drowning cyclists in the middle of the night!
I've just remembered what my worst experience on a bike was ... (how could I forget!)
Our Brad had just won the Tour de France and Cav had taken the final stage -
again! It was a sunny day and a mate had cycled over so we decided to go and do a hilly little local loop to celebrate.
We cycled along the A646 to Mytholmroyd, a couple of flat miles. We were only doing about 15 mph but I seemed to be struggling to stay with my mate. I probably needed a while to warm up?
We turned right and soon passed the sign marking the start of the Cragg Vale climb. It ascends 968 ft in 5.5 miles, a mere 3.3% average. It is not a hard climb, with only a short section of about 8% midway.
Suddenly, Cragg Vale morphed into Alpe d'Huez and my mate became Contador! Effortlessly, he danced on his pedals and sprinted away from me on the intimidating gradient.
Reality check: Er, no, this was Cragg Vale, and the cyclist disappearing into the distance without even trying was my mate. I was terribly out of breath and gasping on the early 2% slopes. I was riding in a tiny gear and only doing about 2 mph. Something was wrong - I felt like I was dying on my bike!
The rest of the climb was awful and it took me nearly an hour. I rested at the top and then carried on to complete the rest of the 19 mile loop, got home, and collapsed in a heap on the stairs leading up from my kitchen. My pal made me a big mug of tea which I barely had the strength to drink.
Those of you have looked inside my 'GWS' thread will know what had happened ... I had developed a DVT (blood clot) in my leg, which led to a pulmonary embolism (feckin' big blood clot in my lungs!) - I literally had nearly died on my bike!
I ended up getting very ill and being carted off to hospital.
I've been terribly breathless on my bike lots of times, but normally it is after doing something silly like dragging my overweight body up a 20% climb. Experiencing it doing 2 mph on a tiny drag was no fun at all!
