Any chance of adding rests in lower where you don't feel the need?
Any chance of adding rests in lower where you don't feel the need? Even poor rests can help sometimes. I have found that resting before you need to rest can help push through a section where there are no rests.
@iainthe "drained forearm" hypothesis is interesting, in terms of what to expect on future multi-day efforts.To rephrase it as a metaphor, are you saying that after several consecutive days of running, one would still be able to run a decent 1/2 marathon, but wouldn't run a 1/2 mile any faster than his 1/2 marathon pace?
