8km-3km-8km MP

By adding in some quicker pace kms in the middle we induce fatigue. So the first 8km at marathon pace should feel comfortable, but then once we’ve hit the half marathon pace we will then be working harder to maintain MP for the 2nd block. An ultimately that’s what will happen on race day. The same pace, but different RPE’s and this session trains us for that. Enjoy. You got this.
