1. The 2 phones

A start phone and a finish phone, both with Time trial mode switched on. The gun time is never used.

2. Using Time trial mode on the phone

First, turn it on. Open the app's Settings page and switch on Time trial mode (cycling events). Do this on both phones, as the switch is kept on each phone. Then, for every rider, it is three steps:

1. Press Record Time the moment the rider crosses the line. The exact time is saved on the phone and appears as a small time chip at the top.
2. Type the rider's number on the keypad and press Enter number & Save. The time is saved against that number.
3. Ready for the next rider. The button goes back to Record Time.

3. How the system works out the net time

Each rider's net time is their own finish time minus their own start time:

Here are three riders sent off one minute apart, as the system sees them:

• Position is the order of the net times, fastest first. Rider 12 finished first, but rider 13 started a minute later and rode faster, so 13 is 1st.
• Gender and age category positions are worked out from the riders' details.
• Every rider needs both a start time and a finish time to get a net time.

4. Watch it work (animation)

Three riders are sent off a minute apart. Watch the start and finish times being saved first, the numbers added afterwards, and the results sorting by net time.

5. Setting it up

1. Create the event. Choose the event type Net Time Event (Start & Finish - 2 timing points). It creates the race and two timing points for you: Start and Finish.
2. Leave the gun time Not set. Each rider is timed from their own start time. In your event menu, Gun time should say Not set.
3. Add your riders. Add them one at a time, or import a CSV with the number, name, gender, date of birth and club. Ages are turned into age categories automatically.
4. Set up the phones. Open the timing app on each phone, enter the event password (shown in your event menu), and in Settings pick that phone's timing point: Start or Finish.
5. Switch on Time trial mode. Still in Settings, switch on Time trial mode (cycling events) on both phones.
6. Run the race. Press Record Time as each rider is sent off, and again as each one finishes, adding the number each time. Results build up live.
7. After the race. Open the Results tab to check the net times, and print the reports. Riders can also see their net time on the public results page.

6. Tips for marshals

• Press Record Time first, always. Press it the moment the rider is sent off or crosses the line, then deal with the number. The time is already saved.
• Several riders together? Press Record Time (or + Time) for each one, then add the numbers one by one. Tap a time chip to choose which time the next number goes to.
• Could not read a number? Press No number to save the time anyway. Open the Log on the phone, or Raw Times in your timing account, and add the number afterwards.
• Every rider needs a start time. With no start time, a rider has no net time. If someone is missed at the start, add their start time in Raw Times and their time appears.
• Wrong number typed? Fix it in Raw Times and the results update.
• Check the clock matches. Both phones take their time from their own clock, so check they show the same time before the first rider goes.
• Accidental double times are fine. If the same number is saved twice at a point, the earliest time is the one that counts.

7. Results and reports

8. Summary

• 2 phones: Start and Finish, both with Time trial mode switched on.
• Time first, number after: press Record Time, then type the number and press Enter number & Save.
• No gun time: each rider's net time is their finish time minus their own start time.
• Live results: net times and positions appear as riders finish, with printed reports at the end.

Press the button on the line, add the number when you can, and every rider gets an exact time.
