Well Lords Rake is shorter nad has 150' less climbing than Foxes Tarn, but Foxes Tarn has a far lesser chance of being crushed to death by a large boulder. The stonefall hazard in Lord's Rake is just not worth it IMHO.

I ran from Scafell PIke to Scafell on Sunday (as part of a 3 day training-BGR in wonderful weather) via Foxes Tarn and it cost me about 12 mins, i.e. i was 12 mins slower than going via broad stand.

Enjoy your run!
