Races/Sweden
Training plan for the Ultravasan 90
Saturday, 21 August 2027 in Sälen, Sweden. That is 39 weeks away.
When a build would have to start
OLTRA plans a block of a length that suits the distance, then works backwards from race day. For this one:
100K — a 24-week build, 6 runs a week
Starts the week of 1 March 2027 — 15 weeks in hand.
On the day
One distance: 100K. Entries, course and timings are vasaloppet.se’s. They decide when entries open and close, and whether the race runs at all — OLTRA sells nothing here and takes nothing from them.
The date here is the one the organiser published, rechecked every 1 hour against the list. Confirm it on their site before you enter.
