Your Brick Run Starts Too Fast: Build a Bike-to-Run Pacing Card

If your first steps after the bike feel deceptively easy, use a pacing card to follow the run your coach or existing plan actually assigned. Before the ride, write down its opening cue and first check point. During the run, compare what you are doing with that plan instead of deciding the pace from the first few strides alone. Afterwards, save the observation for your next plan review.

A bike-to-run “brick” is a combined session, but its purpose and intensity depend on the programme and athlete. This card is a way to execute and review an existing session. It is not a new workout, a universal opening pace or a replacement for individual coaching.

Why make the decision before you get off the bike?

The first run segment can feel different from a run started fresh. In Triathlete’s March 2026 discussion of brick training, coaches describe using the bike-to-run transition to practise pacing and explain that the right session depends on the athlete and purpose. An observational study of elite triathlon racing also reported a faster opening run segment than later laps in its field. That race finding does not set a training target for you. It simply reinforces the value of checking what actually happened against a plan.

A watch can help with that comparison if your plan uses pace, time or effort data. It does not make an unplanned fast start the right one. Likewise, a strange first-minute sensation is information to note, not an instruction to chase a number.

Copy this bike-to-run pacing card

Save these six lines in your phone or on paper. Fill them with the words and measures from your own plan before the session. If a field was not specified, write “not set” rather than inventing a target.

My bike-to-run pacing card
1. Bike-session instruction I am following: __________
2. Planned run intent, effort and opening cue from my plan or coach: __________
3. First planned check point (time, distance or landmark): __________
4. What I will compare there (planned cue or target versus actual observation): __________
5. What my plan says to do if I am ahead, behind or unsure: __________
6. After the session: actual opening split/effort __________; conditions __________; how it felt __________; question for my coach or next review __________

Keep the card short enough to glance at safely before you start running. Set up any watch screen or notes while stopped; do not read a phone while riding or cross a road to check a split.

A worked example without a made-up pace

Suppose your current plan already says to finish the ride as written, begin the run at its stated comfortable cue, and review effort at a familiar path marker. Your card can say: “Bike: follow today’s plan. Run-out: use the coach’s comfortable cue. First check: park path sign. Compare: cue and watch observation with the plan. If I am unsure: follow the plan’s instruction or make a note for my coach.”

At the marker, you have a useful comparison. Perhaps the opening felt relaxed but the recorded pace was quicker than the plan intended; perhaps it matched; perhaps the watch signal was unreliable. Record which happened. Do not turn this example into a fixed interval, split or correction for every athlete.

Use the result to improve the next decision

• Before the session: write the card from the current plan, including any instruction for the bike finish and run opening.
• At the transition: recall the opening cue. Make the first comparison at the check point you chose in advance, in a safe place.
• Afterwards: record the first observation, how it felt and what happened later. If the result conflicts with your plan or you repeatedly cannot judge the opening, bring the note to your coach or qualified adviser before changing the session.

Conditions, route and equipment can affect what a split means. A single reading is a conversation starter, not a verdict about fitness. If you are new to combined sessions or have a medical concern, use an appropriately qualified professional to set the training, rather than this card.

Your next step: copy the six-line card and fill its opening cue and first check point from your next already-planned bike-to-run session. Keep the completed card beside the session so you can compare the plan with what actually happened.
