True-cost calculator

What does a race really cost?

The entry fee is only part of it. We add modelled travel and accommodation for a typical runner from your region to estimate the true cost to the start line, giving a rough comparison rather than a quoted travel price.

Estimates combine sourced entry fee with region-based travel and accommodation assumptions. Race pages show the stored modelled true-cost figure and provenance.

How the estimate is built

Entry fee is a sourced fact. Travel and accommodation are modelled estimates for a typical runner from your region, computed under our published cost model - never presented as a quoted price.
