Dificuldade de corridas em trilha: avaliação do percurso – PONTOS ITRA

Recentemente a International Trail Running Association (ITRA) anunciou, em virtude da pandemia, o congelamento do Índice de Rendimento dos atletas de corrida em trilha no ano de 2020.

Em dois posts vamos falar aqui da diferença entre Pontos ITRA e Índice de Rendimento.

Iniciaremos falando sobre Pontos ITRA. Vamos lá!

Dificuldade de corridas em trilha: avaliação do percurso.

Conhecer de forma precisa a dificuldade de uma corrida em trilha permite aos corredores verificar se podem ou não participar da prova com base na sua aptidão física naquele momento.

A ITRA avalia e pode certificar os percursos dos organizadores de corridas que assim desejem.

A distância e o desnível positivo a serem percorridos são analisados para calcular o esforço necessário e é expressado em Quilômetros (Km) de Esforço (Km-esforço).

Baseada nos km-esforço, a prova se classifica em uma das 7 categorias de corrida em trilha, vão de XXS (Ultra Ultra Curta) até XXL (Ultra Ultra Longa). Segundo esse nível de dificuldade são atribuídos pontos que vão de 0 (zero) até 6 (seis) os chamados Pontos ITRA.

Categorias Pontos ITRA Km-esforço e Tempo estimado do ganhador. Tempo baseado em um atleta com Índice de Rendimento de 850 pontos (explicaremos em um próximo post).

CategoriaPontos ITRAKm-EsforçoTempo aproximado do ganhador
XXS00-241h
XS125-441h30-2h30
S245-742h30-5h

L4115-1548h-12h
XL5155-20912h-17h
XXL6>=21017h

Os pontos ITRA servem para certificar a experiência do corredor, vamos entender como isso funciona.

Os Pontos ITRA servem como unidade de medida para indicar o nível de dificuldade de uma corrida, seu valor expressa a relação entre km a serem percorridos e o esforço necessário (km-esforço), calculada com base na distância e o desnível positivo da corrida.

Dada pela Fórmula:

Distância da Prova em Km + (Altim Positiva/100) = X

Isso nos dá o dado base do Km-esforço, temos ainda que considerar o número de Postos de Reabastecimento disponibilizados pelo organizador durante o percurso. O que é um resultado obtido pela Fórmula:

(Distância da Prova em Km + (Altim Positiva/100))/N P Reabst = Y

Se esse resultado Y for maior que 13, a prova não sofre nenhuma penalização em seu resultado da primeira fórmula, a que nos deu o resultado X. Porém se for menor ou igual a 13, começa a sofrer penalizações de decréscimo de Km-Esforço.

Somente depois de realizar essa divisão pelo número de Postos de Reabastecimento é que saberemos em qual das 7 categorias a corrida se enquadra e com quantos Pontos ITRA ela irá bonificar aqueles atletas que concluírem o percurso dentro do regulamento estabelecido para a prova.

Vamos a um exemplo:

A prova Travessia da Costa possui distância de 36km e Altimetria Positiva acumulada (D+) 1900m

A prova terá 2 Postos de Reabastecimento. Vamos aos cálculos:

Distância: 36km

D+ = 1900m

Postos Reabast: 2

36+(1900/100)=

36+19= 55

Vamos verificar agora se a prova terá decréscimo em virtude da quantidade de Postos de Reabast:

(36+(1900/100))/2=

((36+19))/2=

55/2= 27,5

Ou seja, maior que 13, com isso não sofrerá decréscimo em sua pontuação de Km-Esforço, mantendo os 55 Km-Esforço, que quando comparado com a classificação abaixo se enquadra numa prova de 2 pontos. E se comparada com a Tabela anterior se enquadra numa prova “S”, “Short”, ou seja, Curta.

Sendo as provas classificadas e pontuadas conforme abaixo:

• 0 pontos ITRA para km-esforço entre 0 e 24

• 1 pontos ITRA para km-esforço entre 25 e 44

• 2 pontos ITRA para km-esforço entre 45 e 74

• 3 pontos ITRA para km-esforço entre 75 e 114

• 4 pontos ITRA para km-esforço entre 115 e 154

• 5 pontos ITRA para km-esforço entre 155 e 209

• 6 pontos ITRA a partir de 210 km-esforço


Cada vez que um corredor concluí uma corrida, acumula automaticamente a quantidade de Pontos ITRA correspondentes a corrida que participou. Chegue em primeiro ou em último, acumula a mesma quantidade de pontos, pois esses expressam a experiência do corredor e não sua performance.

Corrida após corrida, o atleta acumula Pontos ITRA e comprova seu nível de experiência como corredor de trilha. Esta experiência lhe dá acesso a corridas particularmente técnicas destinadas a corredores com mais experiência. Alguns organizadores pedem aos participantes que comprovem sua experiência para garantir a segurança em seus eventos.
