Assumption of risk

Not medical or safety advice. Plans, paces, fueling, turnaround times, tide or current estimates, and trip estimates are general calculations from the information you enter, and they may be wrong. Exercise, endurance events, hiking, cycling, paddling, and time outdoors carry a risk of serious injury or death. Consult a physician before beginning a training program, especially if you are pregnant, injured, or have a health condition. Check official weather, trail, park, tide, and water conditions, carry the safety gear the trip requires, and turn back when conditions require it. You participate at your own risk. Fueling suggestions are not nutritional advice for allergies or medical conditions.

What the card contains

Moving time and total time, with your breaks included.
Naismith on the climbs, and Tobler on the grade, so a steep mile is not priced like a flat one.
Summit ETA, planned return, and the latest clock that still gets you back before sunset minus a buffer.
A headlamp warning when the return misses that window.
An optional GPX upload for mile-by-mile gain and loss.

You will see how long the day takes before anyone asks for a card. The turnaround clock stays locked.

Start with the miles

Ang Turnaround ay sketch ng pace mula kay Naismith at Tobler, hindi gabay at hindi ulat ng panahon. Umalis nang mas maaga kung may bagyo, mabagal na grupo, o rutang hindi mo alam. Hindi ginagawang ligtas ng headlamp ang huling pagbalik.
