Reddit reviews The Competitive Runner's Handbook: The Bestselling Guide to Running 5Ks through Marathons

From this book, each 1 degree increase over 60F is about a 1 second increase in pace, amplified by humidity and direct sunlight.

I recommend checking out The Competitive Runner's Handbook
( http://www.amazon.com/Competitive-Runners-Handbook-Bestselling-Marathons/dp/0140469907 ) - no affiliate link.

Bob Glover basically covers running from start to finish. He talks in depth about side stitches (and seemingly everything else), and his strategy is just to power through them.

I haven't lived in the city for a while now so I'm not up on groups but someone here will certainly chime in. There must a ton of speed workouts online. The first training book I bought, which I still refer to as 'the bible' was written by a husband and wife team who ran (run?) running groups in the city: this one.

I like it because they offer a lot of practical advice to new racers. My $.02.

edit, ran, past tense: https://www.nytimes.com/2015/10/25/sports/after-37-years-of-guiding-new-york-runners-ready-for-a-new-path.html

When and how should I increase my distance? Running about 20 miles a week. 5 miles 4 days a week. I'd like to keep increasing my distance and run further.

Also any books you recommend? I currently I have the jack daniels formula but it may not be the best book for beginners as there's a lot more running science than I probably need as a beginner.

There's a book my mom recommended by Bob Glover called The Competitive Runner's Handbook: The Bestselling Guide to Running 5Ks through Marathons
