Elite 3315 Miami | Subject: Outside Magazine: interesting tid bit on increasing run performance just got the new Outside Magazine (August), this is based on the journal of Medicine & Science in Sports & Excercise. supposedly runners who had a 10 oz slushie (ice and sugar water) could run 19% longer in 93 degree heat. apparently the reasoning is it can drop your core temp by 1/2 degree or more... pretty interesting....i hope there will be slushie machines at the next run event. |

Veteran 200 Summerfield, NC | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance Allen Lim talked about this in one of the last issues of Bicycling, specifically how it pertained to Lance. Pretty interesting article(for Bicycling), mostly about Lim and his training approaches and how they relate to LA. |

Member 84 Boston, MA | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance Interesting...Why a slushy and not ice cold water or something else cold? Were the performance gains only due to the cooler core temp or was there more too it (ie. lots of sugar)? |

Master 2210 Columbus, Ohio Coaching member | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance I think a slushie would be colder than ice water. The closer you can get the ice to the water molecules (surface area) the colder the water gets. I think adding salt makes it even colder because the melting temp of the ice goes higher. (or lower? I'm not making sense....) Wonder if the slushie has a little sodium in it.... |

Veteran 480 | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance It's all about surface area of the ice. Slushie has greater surface area of ice crystals than ice cubes in water, where most of the crystals are inside the cube. |

No doubt it does, plus the colorant will likely have some kind of salt (in the chemical sense), AND the sugar can cause the melting temp to be higher (therefore, the slushie--which has some solid, some liquid--is colder than freezing). Surface area isn't going to make a difference if everything you're sucking down gets melted. I'm a big fan of stopping for a popsicle during long runs ... also, I live in the tropics. |

Master 2210 Columbus, Ohio Coaching member | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance So how do you keep your drinks cool? Do those insulated bottles really work? I start out with drinks I have kept in the fridge or freezer all night, and in the summer they are warm within a few miles. There IS a slushie machine at one of the gas stations on the Rev3 Cedar Point course. Maybe I will put that in my race plan, to run there and get one, LOL. |

Master 2210 Columbus, Ohio Coaching member | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance And yes, I perform WAY better when it's cool. My last training ride, it started raining, and we were nice and cool for a couple hours. It made a huge difference in perceived exertion. |

Personally, I choke on really cold water at aid stations, and prefer air temp water. After workout I can take on cold drink. |

Melon Presser 52116 | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance Slushie make Yanti happy. Happy Yanti run better. Dunno about faster. I assume I run better in cool weather, mainly because I think anything cooler than what I currently run in would be good, but I get pretty cranky and uncomfortable if it's below 70. |

Pro 6582 Melbourne FL | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance My first brain freeze was outside a 7-Eleven when I was 11 years old drinking a slushie during summer vacation, you never forget that! Nothing new with this, marathoners were wearing ice/cool jackets to bring down their core temps before the start of the 2004 and 2008 Olympics. |

Pro 5361 | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance There's a huge energy difference between ice at 32 degrees and water at 32 degrees. A slushy allows you to drink ice, and ice will absorb a lot more energy (heat) during its phase change. it's not rocket science, and the relationship between outside temp and max performance has been long established. This isn't surprising at all. |

The thing is the more you read about "breakthrough" research the more you realize most of it is common sense. The hard part is figuring out how to relate to real life. Sure slushie consistency is better then regular water but how many of us have that option midway through a long run in BFE. So you freeze half a water bottle and go with the melt effect. |

I used to choke on really cold liquids, but the other day I found out I can chug an ice-cold full-fizz Coke in less than 15 seconds. I guess it just had to be hot enough and I wanted one bad enough and didn't want to stop running long enough. |

Conrad Stoltz had a bag of ice in a cooler for his T2 at the Richmond xterra, I think the ice was in a bag he could sort of wear on his back or something.. but now I can't remember where I saw the pictures. It was 90-95 or so that day and very high humidity and he smoked it on the run. |

Subject: RE: Outside Magazine: interesting tid bit on increasing run performance I think with the slushie you would be getting actual ice into your stomach, as with ice water you would only be getting the chilled water. |

Master 1433 Calgary, AB | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance I bring a small battery operated slushie maker (like the magic bullet) and keep it in my transition station with my foot wash tray and bucket. Don't you? |

Elite 4048 Gilbert, Az. | Subject: RE: Outside Magazine: interesting tid bit on increasing run performance Just a side note: While the slushie WILL cool you down and help with core temp rise, you can't absorb cold liquid very well, the body has to get it to near body temp before absorbing the majority of it. So, you ARE diverting some energy into heating your stomach contents. John |
