Masters’ record plans
Sixteen years later, Powell, who admits that his weight can be problematic – he has been as heavy as 104kg (230lbs), when his jumping weight was 75kg (165lbs) – has his eye on another World record, for Veterans or Masters, currently held by Aaron Sampson of the USA, at 7.68m.
“I’ve been wanting to do it for the last couple of years, but it’s difficult to train as well as to coach. I started to train about two months ago and the first thing I had to do was lose some weight, to get down from 100kg and my goal was around 85kg. I was well on my way, and I was in training and jumping over seven metres over half of an approach and based on that, from a full approach I would have been capable of going over 7.40m and I figured, okay, another 5kg or so and I’d be ready to jump over 7.60m.
“Then one day when I was in training, I did a plyometric workout I wouldn’t have my top jumpers do. But I was feeling so good, I felt like my old self and I was running 60 metres, and I said, I feel great, and I did a little bit more and I felt something at the back of my knee, and the next morning it was the size of a grapefruit. That was two and a half weeks ago, and it still hasn’t healed completely, it’s taking its time. My goal was to go after the record at the Modesto Relays on May 5, but now I think I’m going to wait till the summer, probably at Bad Langensalza in Germany, a small jumps meet, because I want to break the world masters’ record there.”
