Besides ski racing, I've raced triathlons since 1986 and have watched the
pros over those years. It seems like some of them lose common sense when it
comes to how much training to do, especially the ones doing Ironman races. I
read stories of weekly totals of 15 miles swimming, 450+ on the bike and
another 60+ running. Some of them really toasted their bodies and have
medical problems. A few were able to come back after a couple years off, but
didn't seem at quite the same level. Scott Tinley and Peter Reid come to
mind.



my rule of thumb is biking hours = running hrs x 2=rollerskiing hrs x
1.5.

Probably, measuring the amount of heartbeats would be appropriate for
the training load but you probably have to take the derivative? B/c
an exercise at 150 bpm (biking) is 2x as easy (guesstimate) as an
exercise at 170 bpm ( running), but the 2 numbers are only 10-20%
different.
