Hybrid fitness race pace calculator

How the estimate works

The calculator multiplies your average running pace by the number of intervals, adds each station estimate and then adds one total transition allowance.

It deliberately keeps each assumption visible. If the target depends on an unrealistic wall-ball or sled split, the breakdown shows that immediately.

How to make the target useful

• Use recent compromised-running sessions rather than a fresh 1 km personal best.
• Time complete station efforts under the movement standard you expect to use.
• Include a realistic transition allowance instead of assuming zero.
• Recalculate after a rehearsal and compare the estimate with the actual session.

Share your plan with a coach or partner

Once every time is valid, “Share this race plan” sends a link that opens this calculator with your exact running pace, interval count, transition allowance and eight station splits. On a phone it uses the device share sheet; elsewhere it copies the link.

“Copy plan summary” copies a plain-text list of every split, the totals, the estimate limitation and the same link, ready to paste into a coach or doubles-partner chat.

The plan lives only in the link itself: nothing is stored on ScoreRep, no account is needed, and only numbers are accepted. Whoever opens it can change any value or reset to the defaults.

Add this calculator to your website

Coaches, gyms and clubs can put this free calculator on their own training-resources page. Athletes get every input, the same breakdown and the same planning limitation, and “Open full calculator” takes their plan to this page in a new tab.

1. Copy the embed code below.
2. In your website builder, add a custom HTML block (often called “Custom HTML”, “Code” or “Embed”).
3. Paste the code, keep the credit link underneath the frame, and publish the page over HTTPS.

The calculator runs inside the frame. It adds no script to your page, does not read your page’s address and sends nothing an athlete types to ScoreRep.
