Here are some helpful resources that I have put together including favorite articles, favorite books, cool products, and useful calculators / tables.

### Calculators, Tables, and Conversions:

Treadmill Pace and Incline Table. This table is great at helping you figure out what incline setting to use on a treadmill and for giving you a general idea of how difficult your workout was. It is not as precise as the calculator linked below, but it is simple and only takes a moment to use. I recommend printing and laminating a copy to leave on your treadmill.

Incline Calculator. This is a more robust version of the table linked above. This calculator allows you to enter in a specific speed, incline, and body weight. It then calculates the equivalent speed if you were to be running on flat ground. However, this calculator does not account for differences between indoor and outdoor running such as wind resistance. It only adjust for bodyweight and incline.

McMillan Running Calculator. If you don't want to pay for professional coaching, the tables here offer some of the best free advice you can find. You can enter your current and goal race times, then the calculator gives you suggested training paces for a variety of workouts. Since it doesn't have much data to work with, it has to make a lot of assumptions. For a typical runner, I find the suggested paces to be quite accurate, but it won't be ideal for everyone.

Vertical Feet Per Minute. This table shows your ascent rate at a variety of speeds and inclines. While ascent rate is correlated with effort / difficulty, it is not the only contributing factor. The less steep the incline, the more difficult it becomes to maintain a high ascent rate (think about it: you can't climb at all on flat ground, and imagine how long it would take to climb 1000 feet on 1% incline). However, many athletes still like to do workouts at fixed ascent rates, or know how long it would take to summit a particular peak at a certain speed/incline.

Using Lanes Other Than Lane 1 on the Track - like most runners, I naturally gravitate towards running in lane 1 when doing speed work on the track; the math is simple; 1 lap = 400m. But, running on the inside lane places more stress on the joints and is likely to cause injury if you run great distances on the track. I've lately been doing some marathon pace long runs the track and wanted to know exactly how many laps I needed to run in outer lanes, instead of relying on my Garmin. This calculator makes it simple. A conversion I like to remember: 12 laps in lane 3 is a 5k.

Find My Marathon - if you're a marathon runner, this website will help you find your next race and tell you what your goal time should be. Using weather data, elevation profiles, and other course information, this resource will convert your marathon time at one race to another. So if you ran a 3:02:30 at the Atlanta Marathon, it can tell you what you'll run the Boston Marathon in. It also has a cool pacing guide that takes elevation data and pacing strategy into account, rather than just spitting out even mile splits to follow. It has every marathon in the U.S. listed, so it is a great resource for planning your next race.
