Soon, Richard Reed stopped for another drink.
And then, you guessed it - Richard Reed began to grow another small bit in size.
And remember, his clothes didn't grow with him, so his tracksuit began to feel tighter.
Richard Reed felt like his tracksuit was as tight as clingfilm. "I need to have a word with the dry cleaners about my clothing." he muttered.
But it wasn't just his tracksuit growing, oh no. He immediately felt his feet beginning to chafe in his white sneakers.
SO, Richard Reed carried on with his jogging... or tried to. He could barely move his legs and arms.
Richard Reed found out that his tracksuit was now so tight, he could hardly walk, never mind jog; he was now reduced to a awkward staggering.
"What is going on?" he muttered. "I seem to be slowing down in my jogging!"
He had another drink from his water bottle, and then...
well, you know what happened - he grew another small bit in size.
