Coach a new or returning rider to commute by bike with confidence: a bike readiness and fit check, calm route scoring, a two-week practice ladder, traffic skills, gear by priority, sweat and weather plans, locking, a commute-day checklist, troubleshooting, and a progress log.
Plans a day hike leg by leg. Estimates time with Naismith's rule and Langmuir's descent corrections, adjusted for terrain, fitness, pack weight and breaks, gives clock times for each leg, checks the finish against sunset and the latest safe start, and works out water to carry between refills and snacks to pack. Flags after-dark finishes, long dry stretches and hard terrain late in the day. Includes a stdlib Python planner with --self-test.
Compares commute options - car (fuel or EV), transit, bike, e-bike, walking, day-share mixes and park-and-ride legs - per month and year with cash cost, door-to-door time, time cost at your own hourly value, cost per trip and CO2. Picks pass vs pay-per-ride for the days you ride, separates car running costs from fixed costs, and shows the break-even value of an hour. Includes a stdlib Python calculator with --self-test.
Plans where every batch-cooked portion lives after a meal prep session: which stay in the fridge, which go in the freezer on prep day, when to move each to the fridge to thaw, and what goes on the labels, using conservative USDA fridge and freezer times. Flags meals planned past the use-by date, foods that do not freeze, shortfalls, leftovers and a full fridge. Includes a stdlib Python planner with --self-test.
Builds and reviews 5K to marathon running plans: a tested script checks weekly volume jumps, long run share and progression, hard and back-to-back days, rest and cutback weeks, peak timing, and taper, then the skill explains the risks in plain language and proposes a safer week-by-week plan.
