Frequently Asked Questions
Is there a run walk pace calculator?
Yes. The run-walk calculator takes your run pace, walk pace and interval pattern (for example 4 minutes running, 1 minute walking) and returns your overall pace and finish time for any distance. A 9:00 run / 15:00 walk mix on a 4:1 pattern averages about 10:12 per mile.
How do I convert cycling to running (run to bike conversion)?
The common coaching rule is 1 mile of running equals roughly 3 miles of cycling, or about 10 minutes of easy running per 30 minutes of easy riding, because running loads the legs far harder per minute. For a training-stress match use heart rate: ride until you have spent the same minutes in the same zone, remembering that cycling heart rate runs 5 to 10 bpm lower. Build the two sides of the plan with the running pace calculator and the cycling calculators, or let the triathlon plan generator balance run and bike for you.
Which calculator do I use for a cycling to running conversion by calories?
Compare the calories burned running calculator with the cycling calorie calculator at the same weight and duration. Easy running burns roughly 100 calories per mile for a 155 lb runner; moderate cycling at 14 to 16 mph burns about 10 calories per minute, so a 60-minute ride matches a 6-mile run.
How long should recovery be after a hard run?
Use the recovery calculator: it scales rest from workout intensity and duration. As a rule, one easy day after a threshold session, two after a long run over 90 minutes, and three to seven after a race, longer for a marathon.
