Races/United States
Training plan for the MadCity 100K
Saturday, 10 April 2027 in Madison, United States. That is 20 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:
50K — a 20-week build, 5 runs a week
Starts the week of 16 November 2026 — 0 weeks in hand.
100K — a 24-week build, 6 runs a week
Not enough room left for the full build.
Too close? The next one
The organiser runs this the second Saturday in April, which puts the 2028 race on Saturday, 8 April 2028. That date is not announced yet, so check it before planning to it — but a 100K build for it would start the week of 18 October 2027.
On the day
Distances: 50K, 100K. Entries, course and timings are runsignup.com’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.
