running
i usally run outside and it is around 25 degrees. then i ran yesterday on a treadmill in 70 degrees and it was harder i think just because my heart was alot higher due to the temp. so am i handicaping myself by running outside in the cold. my friend only runs on his treadmill and today he ran outside and can run the same pace at 10 beats per minute slower on his heart, which means when he is hittingnhis zones at 70 degrees he acually is running above his zone pace based on his heart rate and then goes in cold weather and if he was to hold the same heart rate he would be about a minute per pace faster outside. my race will be in texas in may. it will be hot. should i train indoors at 70. i feel like iam at a handicap outside because if i was holding same zone pace in door at 70 it would really faster outside based on percieved effort cause my heart is lower in cold. please help

Different speeds on the treadmill are common, and can be related to temperature/humidity, ventilation, mechanics, and calibration. Too many variables to say what's at play. Working hard is working hard. Do that, and you'll get faster.
Shawn, are you using a strong fan when you are running indoors? If I don't cool myself when running indoors, my performance suffers.
Depends on what your goal is. I've run without a fan when I was trying to acclimate for a race in Hawaii. But usually, I use a fan when I do hard intervals on the treadmill, to be comfortable as well as avoid spraying sweat on the folks all around me. And in my power penthouse (aka pain cave), I am biking outside on a deck, and still need a fan for FTP and VO2 max intervals anytime the temp goes over about 50F. Keeping your core cool(er) allows you to achieve a better training effect by working harder. And, as the logo say, "work works".
2x on Al's comments. With no fan, your core temp will rise significantly during hard efforts and you will be able to do less work than if cooled. The RPE will seem high but the max work and adaption will be less. 2 good fans is recommended.
The majority of your heat adaption should take place in the 3 weeks before your race.
Work works.
It's heat and humidity. The heat I can deal with, it's the humidity that gets to me... and I live in Houston. The downfall of many out of towners during IMTX last year was the humidity.
