When should i take a break off training for cross country?

I run everyday to train for cross and i have been told to not train everyday so that i am not tired for high school cross. I trained everyday before track started and i already became the best 7th grade distance runner for my school. I kept training everyday now im the top cross country runner. I wan’t to know if i should take atleast one day off a week to rest. Because i want to stay as i am now.

Can I train for a triathlon in 3 weeks?

I’ve been exercising for half an hour a day for a month already (alternating swimming and running). And there is a triathlon in 3 weeks. Today was my first day biking. I was a great cross country runner in high school (i just graduated from college) and get in shape pretty quickly. Do you think this is enough time to legitimately train?

What are some good running shoes for cross country running?

Does anyone know of any specific running shoes that won’t cause shin splints or stress fractures due to running on different terrain? I am a cross country runner and i get shin splints easy when i run on different surfaces. Thanks you for your help (:

How is this idea for cross country training?

I’m a cross country runner, and this is an idea I have for training, tell me what you think of it. Ok, well to start off the focus of my training is to improve my muscular, not cardiovascular, endurance. I have absolutely fantastic cardiovascular endurance, and the only thing preventing me from running faster times is that my muscles just get wasted after a while and I can’t keep the pace of my first half. Again, its not cardiovascular, as I can hold my breath, have a conversation, all of it and during a race. And still get great times. So, to improve my musuclar endurance, my idea is to , staring today, do stairs at absolute max, 5, up and down, at a time (its about a hundred steps up). Then do Stassi Squats, and repeat until I am absolutely beyond exhausted. I feel that if I can continue this for a few weeks, perhaps my muscles will be able to keep up with cardiovascular endurance, and I’ll be able to run much faster. Any comments, advice, and the like would be appreciated.
First person says that’ll build cardiovascular, which is true, but won’t going up stairs also build muscular endurance? What can I do to as quickly as possible strengthen that?
