Prepare for Servus Calgary Marathon

A plan built from your answers and your race date.

The race is staged in Calgary, in southern Alberta at the edge of the Rockies. The route mixes city streets with long stretches of pathway along the Bow River, on fast, well-surfaced ground. Late May weather in Alberta is changeable: cold mornings and wind are possible, and so are mild, dry racing conditions.

Four distances are offered: marathon, half marathon, 10K and 5K, spread across a two-day weekend. Exactly which races fall on the Saturday and which on the Sunday has not yet been published. The event is billed as the oldest marathon in Canada still held today.

The formats

4 formats on the program.

When to start

A build for this distance usually runs 12 to 20 weeks. Counted back from race day, that puts the start somewhere between January 4, 2027 and March 1, 2027.

These ranges are working conventions, not a research finding — no trial has compared plan lengths against each other. What matters more is that the plan was built for the weeks you actually have, rather than shrunk down from a longer one.
