DFW running club mark 2!! ALL ARE WELCOME!!!

Keswick round the houses official distance 5.3 miles. My spreadsheet basically uses the reigel formula for working out race times from other races although the fetch site can calculate a different number to the 1.06 used in the official one but i alway reset it back to 1.06 as i have a feeling the several trial races i have done plus the single ultra skew the data a bit.

The reigel formula for those who dont know is

T2 = T1* (D1/D2)^1.06 where T1 is the race time for the race you are using in seconds, D1 is the distance for that race and D2 the distance for the race you are predicting. Off course using excel there is no need to fanny around calculating in seconds

The other one i use is the McMillan website calculator which is pretty similar

Well done on the race KM - its prob just me but your elevation chart looks a bit rude

As the subject of fatalities in marathons came up, hopefully this will put it in some sort of context. It suggests that heart damage is only likely in those runners attempting a marathon on minimal training, ie less than 35 miles per week, but it would be ill advised to attempt a marathon on such little training anyway because the body simply isnt prepared for it:

Cardiac risks
A study published in 1996[38] found that the risk of having a fatal heart attack during, or in the period 24 hours after a marathon, was approximately 1 in 50,000 over an athlete's racing career[39]—which the authors characterised as an "extremely small" risk. The paper went on to say that since the risk was so small, cardiac screening programs for marathons were not warranted. However, this study was not an attempt to assess the overall benefit or risk to cardiac health of marathon running.
In 2006, a study of 60 non-elite marathon participants tested runners for certain proteins (see Troponin) which indicate heart damage or dysfunction after they had completed the marathon, and gave them ultrasound scans before and after the race. The study revealed that, in that sample of 60 people, runners who had done less than 35 miles per week training before the race were most likely to show some heart damage or dysfunction, while runners who had done more than 45 miles per week training beforehand showed few or no heart problems.[40]
It should be emphasized that regular exercise in general provides a range of health benefits, including a substantially reduced risk of heart attacks. Moreover, these studies only relate to marathons, not to other forms of running. It has been suggested that as marathon running is a test of endurance, it stresses the heart more than shorter running activities, and this may be the reason for the reported findings.

I'm not sure you'd get round on less than 35 miles per week anyway - so I guess those most at risk are the slow ones and the drop outs!

And these are the actual stats relating to the London Marathon - as can be seen the risk is extremely small and some of the fatalities may even be unrelated to the marathon itself. As always, proper training reduces these risks to be almost non existent.

It is worth noting that in the first 9 years of the race, when the vast majority of runners were well trained club runners, there were no fatalities at all, further emphasising how the risks can almost be eliminated with proper training:

In 2000, when 32,600 runners completed the race, 4,633 St John Ambulance and 38 hospital contacts were recorded. By comparison, in 1987, when 19,970 runners completed the race, there were 4,984 St John Ambulance contacts and 10 hospital contacts. Totals for the 20 years show a hospital contact rate of 0.13% (one in 787). Hospital admissions are roughly 10% of the hospital contacts, but are increasingly difficult to define, as runners may spend many hours in accident and emergency.
Only those deaths, or collapses leading to deaths, that occur during the Marathon or within the finish area of the race, are considered Marathon deaths. Seven cardiac deaths have been reported in the London Marathon: five from severe coronary heart disease – in 1991, 1994, 1995 1997 and 2003 – and two with hypertrophic cardiomyopathy (HCM, a chronic disorder affecting the heart muscle) – in 1990 and 2001. Five successful cardiac resuscitations have taken place (in 1983, 1988, 1990, 1997 and 1998); all patients had coronary heart disease and were subsequently discharged from hospital. In the millennium race, a young man collapsed at the finish complaining of neck pain and died the following day in hospital following a diagnosis of subarachnoid (brain) haemorrhage.
The overall mortality rate from the 20 years is one in 67,414, or roughly one death for every two million miles run.
