Is "hot" good or bad??
Hi all,
Being a 'handbag' (apologies to genuine handbags out there...) and not riding today or the next couple in BrisneyLand due to the 'oppressive heat' (forecast around 35-39 for the next couple of days...) Question of course is - does riding in the heat actually provide a greater training benefit (compared to 'normal weather') ie. more calories burned, greater actual effort required (not just perceived effort), etc etc. Aside from just 'getting used to' riding in the heat (ie acclimatisation benefit), can I tell myself that I'm actually doing some good by pedalling up the hills with the hot sun baking down, the heat emanating from the roadway 'baking up', and me slowly toasting toa crisp?? Or if I rode, am I just asking to become mega-dehydrated, with out any acompanying mega-fitness benefit to go with it?? Cheers all, Absent Husband (who kind of feels like a wuss, but is looking for some reassurance...) |

Riding in the heat exposes you to higher risk of dehydration, loss o electrolytes and heat exhaustion. Your body has a harder time controlling temperature, especially if th high temp is accompanied by high humidity. Heat stroke cannot always b alleviated by fluid intake and is potentially lethal, though flui intake is a key risk factor. There is little difference in training benefit, as long as you hydrat more often and in greater quantity when training in the heat. However prolonged efforts in the heat will require _significant_ quantities o electrolytes with water, generally 'quite a lot' more than your norma consumption. A cautionary tale... http://www.rice.edu/~jenky/sports/dehydration.html Ritc -- ritcho |

One thing I didn't do on the alpine was tak in enough salt, and paid for it going up Buffalo. I really didn' understand what my body was going through, and even though I wa drinking lots of water, I now understand that my body was rejecting it Also helps explain the nausea I experienced.

Not nice. 62? What is that - your age? Surely not kg??? You must have flown u the Alpine climbs! Ritc -- ritcho |

I came to a grinding halt on Buffalo, unti then I was on track for sub 10, which was my original aim. There wasn' many that were passing me on Tawonga, Falls, but alot flying past on th downhill (more a lack of confidence from me) -- essendon93 |

Thanks for the website tip - actually explained a lot!!
I know I've experienced heat exhaustion only once before... Many years ago (pre wife & kids!!), I rode up Mt Coot-tha (in BrisVegas) on my own, at 1pm on a bright hot day at teh start of February. As I recall, it was about 34 - 35 degrees that day (with reasonable humidity). After struggling to the top, I remember stumbling off the bike, falling over near a tree, and spending the next 20 minutes throwing up/dry retching under a tree. Given that I was a bit of a triathlon superhero back then, I was pretty freaked out. I sat under a tree in the shade for almost an hour trying to cool down, and finished off my bidon of water (the only one I brought on the ride!!). Then tried to work out how I was going to get home - no water, already severely dehydrated, feeling light-headed, and lots of hills to go to my place at Red Hill.... Ended up just being a loooong, slooow ride back. Took me 30 minutes to get from home to the base of Mt Coot-tha, but almost 2 hours to get from Mt-Cootha back to home. When I got back, I stripped off and sat in the shower under the cold water for about half an hour before I felt well enough to move again. Needless to say, I've never let myself get that dehydrated again, or ridden between 11am & 3pm during the warmer months.... Cheers all, Absent Husband (who nows has a lard-arse to drag up Mt Coot-tha as well, making it even harder than before!!) |

I'm still 1kg down from m normal body weight (62) Here's a story about what you experienced. http://www.audax.org.au/faq-susscreen.htm Look at the last story from Michael Carden. I suggested eating almonds to relieve cramps. This came about through m partner Joanne suffering leg cramps at the moment, in the second half o a pregnancy. The usual hydration and stretching only partially helped The almonds are alleged to alleviate the cramps due to the magnesiu they contain. It seems as though one of the causes of cramps can be a imbalance in the levels of things like sodium, potassium, calcium an magnesium in the body. From the various sources we checked out, w gather that it's not just the absolute levels of these chemicals, bu their ratios relative to each other which have an effect on cramping. The issue of hydration and electrolyte balance prompts me to mentio this postscript to the Alpine Classic. One of the Canberra crew dow for the event, young Cath, finished the 200km in fine form and amble cheerfully back to the motel relating her ride to us. Half an hou later, she collapsed vomiting at the motel and was unable to keep dow any water. Her condition rapidly deteriorated as we drove her to th Bright 'hospital' [actually a private medical centre]. A doctor wa called in, and decided to transfer her by ambulance to Wangaratta. Doctors in Wangaratta were very concerned at her incoherence and he failure to respond to intravenous saline. They spent much of the nigh in communication with neurologists in Melbourne, and performed 2 C scans and a lumbar puncture. Cath was not looking good. By 10:00am on Monday morning though, Cath was walking and talkin again, albeit with a fuzzy head and a headache. The best theory so far from the doctors is that Cath drove her sodiu levels dangerously low during the ride by drinking large volumes o water, with inadequate intake of salts. It's a fine line between pleasure and pain... MC -- jazmo |

Geez that last story from audax is a bit scary, because thats exactl what I did, large volumes of water with no sodium intake, and I wa very close to throwing up on Buffalo. Was that from this years -- essendon93 |
