Interval sprints (Running)

[Fiona N]

More seriously, I'd amplify Jimbo's comments about the effects of running. I don't think I ever lost much weight by the process of running (given that I was doing a lot more cycling, in time as well as calories burned, at the same time) but I found that the harder the session, the less likely I was to eat anytime soon afterwards.

I used to run at lunchtimes - usually for about 10km on a hilly circuit which took about 50 mins of fairly comfortable running - and have a sandwich at my desk afterwards. But on the one day a week that I did a measured 5km run with regular 10km road runners (who didn't like my hilly, off-road circuit) we'd warm up with a half circuit of jogging then go flat out round the full 5km in <20 mins (them) or <22 mins (me ) followed by some limping along to cool down. I wouldn't want to look at a sandwich or anything other than a glass of water for about 3 hours after because my stomach always felt so shaken up and vaguely nauseated.

I think you are underestimating Gaz's knowledge. He has lost 23 stone of bodyweight in three years. Three years is time enough to learn about exercising.
He's not a newbie to running.

His question was concerning sprint sessions and energy burn.
Of course he'll lose adipose if he works and doesn't put the energy back.

Carry on Gaz. Don't forget the crash mat.

BTW Gaz, did you get the letter about an M.B.E. ?

I think its more like 25 stone in 2 and a half years of cycling

You sent me a letter about a MBE mate ? are you the queen ? LOL....People like me dont get MBE's...Im just someone who was obese that lost weight, thats all.

I gotta agree, the hard I go, the less I want to eat :-D

Having sprinted for some while , I would not recommend treadmills for sprint intervals for several reasons.

The pick up and slow down is not quick enough and it tends to end up as a 25 - 50 M roll up and roll down which undermines the intense sprint effort.

Treadmills only tend to go up to 16KM/H which equates to 22.5 seconds for 100M or 90 seconds for 400 , too slow for sprint reps and probably 800M intervals at the shortest

The rebound from the treadmill is too great and the surface grip not enough, a decent sprint action will bounce back too much and the feet are likely to slip especially when trying to get up on the balls of the feet in training shoes.

A standard treadmill is not long enough to really allow the stride length to be opened up

if it is sprints you are after Grass or a track would be your best bet.

I agree with the eating comments , after really intense sprint endurance session it was an effort to stop throwing up let alone be able to eat. but a pure sprint session would not affect my appetite.

If it's 12 m/s we'll be seeing you giving Usain Bolt a run for his money

Shhhhh. Gaz is the 2012 London 'Secret'....
