I've just finished the London Marathon in 4hrs 40min. I want to do a half marathon in July.Should I start at the beginning of a schedule or can I just ' jump 'in at say week 3/4 of a schedule and rely on fitness gained during my marathon training
I have just started interval sessions whilst using a HR monitor. Session consisited of 1M warm-up and 1M cool down. Inbetween I was doing 3x1M fast. I was able to keep my HR within the target zone for the first 2 intervals however on the 3rd I had to reduce my pace to maintain the HR zone. Should I keep to the HR zone and reduce my pace or maintain the pace and go above the target zone.
