My friend's idea to plan and track his Trailwalker (HK 100km) results.
All input fields are "green" in colour. There are 3 main parts:

1. Planner
- Title (description of a planner/tracker)
- Target hours (optional)
- Start date and time
- Schedule duration and rest time for each segment

2. Tracker
- (the title points to the same title of planner)
- Check-in time (arrive a check point)
- Check-out time (leave a check point) (if omitted, check-out time = check-in time)

3. Analysis
- (compare schedule time to actual time)

There are some functions to manage different planner/tracker.
Simple. Just see screenshots and try.
