Hi, I'm Twm, I'm 10 years old and have decided to do a 10 x 100 challenge, inspired by Captain Tom, starting at 10am on 10 May to help our local health service. The 10 challenges I'll be doing are... 100 laps of the back-lane; 100 pogo jumps; 100 times up and down the stairs; 100 football keep-ups; 100 star jumps; 100 press-ups; 100 minutes silence; 100 burpees; 100 skips and 100 sit-ups.

Haia, Twm ydw i, a dw i'n 10 oed ac wedi penderfynu gwneud her 10 x 100, wedi ei ysbrydoli gan y Capten Tom, gan ddechrau am 10am ar 10 Mai i helpu ein gwasanaeth iechyd lleol. Y 10 her y byddaf yn eu gwneud yw... 100 lap o'r lôn gefn; 100 o neidiau pogo; 100 gwaith i fyny ac i lawr y grisiau; 100 keep-ups pêl-droed; 100 o neidiau seren; 100 ymwthiad; 100 munud o dawelwch; 100 o burpees; 100 o sgipiau a 100 eistedd i fyny.
