that is still true: marathon starts after mile 20, very good start, may be a little too fast?
thanks. yeah, may be i started a bit too fast, but i felt ok. i didn't run with hr monitor and can't say i was running too hard. it's still true that hard to run marathon on average weekly running volume under 20 miles. my calves didn't feel ready for long runs. no wonder - i had just few long training runs this year. need to put some volume to get ready for boston...
