Races/Switzerland
Training plan for the Bieler Lauftage 100 km
Friday, 11 June 2027 in Biel, Switzerland. That is 29 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 21 December 2026 — 5 weeks in hand.
On the day
One distance: 100K. Entries, course and timings are 100km.ch’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.
