Not every mined block had the full reward . Sometimes this has not been calculated in . And not forget the blockheight , which may differ from site to site . Some sites may deduct proven lost or proven burned coins from the calculated sum . Some say available supply , others Total BTC . You never know how it ' s calculated as long as you don ' t calculate yourself . <| sep |> Best thing to do would be to run more and longer . Try to aim at slightly increasing your training monthly , and also varying the kinds of running you do . I . e . Workouts , long runs , regular distance , intervals , drills along with rest days of course . 400 m repeats on a track once a week are ideal . So say start with 400 m x 6 and with 200 m slow recovery in between . Then about every week move the amount of repeats up by one or two along with increasing your time for each 400 repeat . By the end of a few months try to cap out at around 14 or 16 repeats minimum 75 seconds an interval 75 s are a 5 minute mile pace . Also try a fartlek during your distance runs , 1 min fast and then 2 min slower for your entire distance run . Most importantly treat your body good eat clean stretch and strengthen , can ' t run if your injured ! Best of luck !
